、, ll 11 明 11 明 name ク ロ ス crosstalk component cancellation circuit 3 in the angle
modulated wave signal transmission line, the detailed description of the invention The present
invention relates to the angle modulation e, crosstalk component cancellation circuit in the signal
transmission line The crosstalk component from the modulation wave signal to the break P4 of
the instantaneously connected channel included in the angle modulation wave signal of the
desired channel among the plurality of angle modulation wave signals subjected to V modulation
by separate modulation No. ll- The above-mentioned 1 l l-channel angle-modulated wave 1 g
mixed with the angle-modulated wave signal of this desired channel to cancel, the anglemodulated o R flight level of the earth distribution n-channel is zero or miserable By applying the
sign to a multi-channel record speed circuit by making sure not to lose trade-off when it is small,
the crosstalk characteristic cancellation circuit that can improve the crosstalk characteristic all
times. The whole object of the present invention is to provide. There are a plurality of angle
summers a11 e which are L modulated into separate modulation signals, and as a signal
transmission path, for example, a multi-channel difference signal transmission system which is
self-recorded by 6 channels in a multichannel / channel record . In multichannel / channel
record, multi-channel audio signals are arranged as sum signal and 斧 signal, and angle
modulation is performed with difference 1 g as history 'c' and the angle modulated wave signal
obtained is directly taken as temporary remarks A large number of items are recorded on one
side wall of V next to 0. Because of this, the recording system of the multi-channel record and the
reproduction yarn have two cross talks between the angle modulated wave signals of both sound
groove walls. In this case, the angle of the angle modulated wave signal is changed to generate a
mutual band. In the plurality of angled rhombus A wave signal transmission paths as described
above, if the desired channel / ft fft angle modulation wave signal has a crosstalk J ratio from the
instantaneous channel, intermodulation as described above Distortion occurs, causing distortion
in the horizontal slope output. Therefore, in order to reduce this distortion component, it is
conceivable to control the level of the tone signal of the angle modulated wave signal in
accordance with the envelope of the angle modulated wave signal.発 明 @ i invention invented.
However, in such a method of reducing the crosstalk component in the demodulator, it is not
easy for each station to completely eliminate the crosstalk component. In addition, in the
transmission where the power of the angle modulated wave 1 digit is turned off / off to the work
9 of the demodulator of the regenerative illumination / alteration ai 11 of the multichannel /
channel record, in the prior art There is a problem that the crosstalk% note of the angle
modulated wave signal is deteriorated @ (at the start of playing a multi-channel record) when the
human power of the earthquake A slope signal is turned off from off to load.
Therefore, in the waiting application on the same date as the present application, the nonapplicant deciphers the angle modulated wave signal that says one crossing factor, and cancels
the crosstalk component before A 瑛 and the desired channel And U of the channel that is
momentarily touching, when the wave ex angle 1 harmonic wave number of the channel is zero
or is small, it is Miyamachi to be an angle modulated wave wave number 1 g of the desired
channel / channel. Eliminating the generation output of the envelope detection signal used to
cancel the stalk component Eri, the problem of self-conclusion can be determined Cough-I made
a proposal. Fig. g1 is a cross-talk component hit in the temporary use modulation slope signal
transmission line which will be the ground of the applicant of this Honda. In the figure, “l” is a
desired channel / channel <L5 +, −v is a channel of “n”, “g” is a% 4 channel number 1a

variable tAt counter signal input terminal. In the input terminal 1 (· an angle modulated wave
signal (hereinafter also referred to as an uncorrected signal) S □ of an irregular channel coming
into contact with it, the angle f adjustment (n of the other (i In the following, it is assumed that a
part of (SBSB) m is used as crosstalk, which is also referred to as f instantaneous teggin unle
signal. One-page cha / channel signal SB is twice amplified and extracted by the terminal 3 when
the input level is higher than the storehouse input level. Therefore, KSB 1B is generated at the
connection point (a) between the pain and the output side of the device 3 and the output 狽 1j of
the phase inverter 4 and one end of the resistor R6 and the later At the connection point (b) with
the input end of the opening J variation damping # 5, the -KSR 1B is generated. Here, the input
terminal l is connected to the other end of the above resistance ratio, one end of the resistance
'59' 51'7, and the main channel 1 signal output terminal 9 through the resistance ratio. The
connection point between the resistor 1 and the resistors R2 and f-4 is denoted by (R). In
addition, the other end of 3 R3 is connected to the input 1jIllK of DJ variation 5. Now 14.
Assuming that <kL2, Le, (The impedance of the sharp point is approximately R1, but the signal
KSB is divided by the resistance of 7L and the 1g number divided by the valley resistance value
of R42 and divided by α, αKS (As it happens, it occurs at the mark point. In part (b), the
extinction g is the attenuation weight of the oJ variable attenuator 5, the resistance ratio, and the
valley resistance of the R3 plus 1 division ratio β, J It is divided and occurs at the point (c) as a
signal of one βK1, SB.
2.) Since the main channel No. S □ containing a crosstalk component of δSB at this point (C) has
almost all resistance, and of course, there is a voltage V at point (C). In the following equation. ■
o = SA + δSB + αKSB-βKLISB = SA + (δ + α 1 βK1) 5B (1) The signal KSB at point (a) is
divided by R5 and divided into R5 and supplied to the envelope selector 6 It is supplied to a part
of the input terminal of the voltage ratio softener 8 by the envelope MI detection. Similarly, (B) KS of point b is a resistance 1 (16j ratio, 0 min at a certain rate, envelop taste, nl supplied to the

anti-A modified 1S, the envelope modulation of the angular modulation a and sweet acid ↑ S of
the signal and the crosstalk component is compared with the angle amount of both modulations,
To change. Therefore, when comparing a signal with less crosstalk weight and a larger signal
with each other, a person who is a crosstalk fireflies has a large variation in envelope taste, and
thus, rising! The output of a variety of pots such as 6, 7 and so on when the length of time for
beans is longer than 10,000 hours is longer than 10,000 hours. It becomes a human DC output.

suitable for use in the construction of an unconducted box to make a change in the envelope and
change the envelope, so that the pressure comparison book 8 and the Or change reduction
installation 5 will be made. If the channoll signal of the ship is in love time, unmodulated or if the
angle shift is small, then this is a small amount of summer time in the view of the human power
signal of the @ flow circuit of Listing 1? なくすことになる。 For this reason, the low pass filter I
reduces the signal level of excessive noise or decreases accordingly. As a matter of fact, there is
no power of the field in the second inflow, and the output level of the pressure ratio softener 8
also becomes zero. As a result, the potential of the unintended point in (h) becomes a problem in
the third factor, but this means that the +4 depending corner / near A / store number l no kundai
of the outlet terminal 9 is eliminated, There is no possibility of erroneous movement caused by
variations in circuit elements on the ground. In the non-invention circuit, for example, the output
'IN' of the amplifier 3 is used as a human power signal for the output terminal 9 shown in FIG.
Even if it passes through the circuit which further comprises the same as the third illustration
and the composition vocabulary and t, the initial object can be achieved. Moreover, in this case,
the crosstalk component from the W4 channel, which is 7 channels larger than this Tyanyi A /

or t can be defeated.
As described above, the crosstalk component cancellation circuit in the angle-adjusting liquidconditioning signal transmission line according to the present invention comprises: the first
modulated signal of the angle and the first modulated wave of the channel in contact with the
desired channel. Through the 1st or 2nd modulated wave of 1st and 2nd angle modulated waves
and τ which has a predetermined phase difference with each other and a VC phase angle
different from each other, and the level through the above means. The mixing channel 1100 is
mixed with the breaking angle #f harmonic number of the desired channel in which a part of the
first modulated signal of the angle modulated signal of the adjacent channel is mixed as a
crosstalk component. Third and fourth angle modulated wave signals are obtained by mixing
each of the first and second one-angle rhombus wave signals with a predetermined type to obtain
the third and fourth angle modulated wave signals, and a crosstalk is generated by the combining
circuit. When the person wave of the modulation wave 1g is above the charcoal level, the third
and fourth At least some of the first and second angle modulated wave signals are fully described
above so that the peak values or changes of the envelope of the angle modulated wave signal are
substantially equal. When the summer means is subjected to L di O J control and the above
human power level becomes zero or decreases with time, the above first and second angle
modulated wave signals are substantially added to the angle modulated wave signal of the upper
6Cs shop Tayanonel. Since the above-mentioned level variable means is controlled so as not to be
mixed 7′L in time, the first and second modulated signals of the first and second modulated
signals become unstable when the upper input level becomes smaller. It is possible to prevent
