DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device
used for displaying imperviousness of an empire, for example, output from each channel of a 4channel stereo, and particularly suitable for color display. Generally speaking, the four channels
of the 4-channel stereo are punished right 4111 speakers. pi1 + direction left 41 (It's speaker,
the speaker on the rear left 1 and the speaker on the left side are connected. The display device
is used when it is desired to carefully output the sound output from the speakers in each
direction during deduction of the 4-channel stereo. Conventionally, this display device is a
display system in which a material source is assumed at the center of an oscilloscope 11 cathode-

ray tube display (2) as shown in FIG. 1, and it radiates from the central neck source to four
directions. In fact, since the speaker is emitted 10 to the center from each of the speakers 4
arranged in 5 directions, it is assumed that the viewer is in the center of the * 18cl CRT display
surface, ' If you look at the display state and feel visual confusion. I did not say that I had a sense
of smell opposite to the sense of hearing 1 that actually heard a wolf. The above device was
regarded as the queen's circumstances, and the CRT display was clearly displayed. A single

? PL-(f 'If it is a low-f (150 to 400 Hz) audio system, if it is curved, the processing system 54 jt
in Chapter 1 is ft, and if it is a medium t (400 to 4 KHz) audio signal, the second processing
system 55 Introduce and enjoy.
If the high f (4 KHz to 20 KHz) audio signal is introduced to the third processing system 56, the
HNe low d audio signal PL-? is applied to the input of the polarity shaping circuit 5410, The
characteristic shaping circuit 54 has an output of -7, and a power of one does not change the
polarity of the input signal PL-0 '. Is the polarity of the signal PL-0 'missed and input? Invert and
output. The signal PL-01 DEG FL-02 outputted in this way is applied to the input terminals b and
b 'of the phase shift circuit 542, respectively. This phase shift circuit 542d. For example, use the
phase shift difference 10 ? ? for the No. 14 PL-01 ? and PL-02 ? City 1 that appear on the

system 55 is added to the green matrix circuit of the V axis of the IC oscilloscope through the
forward diode D, and one edge of the pulse superposition circuit 554 'is a reverse diode. The Dsk
is added to the warm +14 matrix circuit of the H axis of the i'i J ? oscilloscope.
Also, the phase shift circuit 562 of the third system ? 56 sets a phase difference of 90 ░
between the signals PL ? (11 ? and PL?02 ?) appearing at the output ends e and e ? of this
circuit. The output of the pulse superposition circuit 564 of the processing system 56 is added to
the blue matrix for the V- of the @r oscilloscope via the 111-direction diode D, and the output of

position where the left 41 + 11 speaker's sound is centered, and the sharp pencil beam red that
extends in the center from the position where the back source is set A signal is displayed. Also,
before the audio signal is input to the phase shift circuit 542 ░ 552.562, since the high, middle

shape. The other audio signals PFL-0, BR-0, and BL- (1 are also processed as described above for
the audio signal PL-0 as described above, and the waveform processing is performed in the same
manner as described below. The origin is set slightly, centering according to the size of the level,
and if it is low, it is painted in blue with% circle, if it is medium back, it is drawn in hensil beam
shape, and it is red in high tone 7) These four sets of audio signals PR-0, B-Lu 0,. As shown in
FIG. 3 and FIG. 3, the comparison with the opposite polarity is carried out for the square wave
signal which is 7 g folded as shown in FIG. According to the display gB of the stop 1 according to
the display gB, since the h source of everyone generated from the speaker in each direction of 4
channels is installed on the inside edge of the brown display surface in the simulated ETJ, the
display 1 ... center If you reminiscing the position of the person on the side, the auditory dove

with "H", which can display the high-pitched, medium-pitched, low-pitched sounds in different
colors, and can also show the extreme pseudo directional characteristics of the sound emitted
from the speaker. There is a great deal of rice bran in the area of relaxation.
Various modifications can be made without departing from the scope of the present invention. As
