Claims DETAILED DESCRIPTION OF THE INVENTION The present invention provides a rotational sound image signal generator useful for measuring effects of 2-n (n is an arbitrary positive integer) channel stereo system. Conventionally, in order to measure the stereo effect with 2-channel to 4channel stereo etc., the reproduced sound for one sound in each direction of the 2- to 4-channel stereo signal must be manually or assy switching circuit according to the necessity. They made a change by listening to the sound image. However, according to the above-mentioned method Q, it was a bad smell, and it was difficult to make. According to the rotational sound image signal generating apparatus of the present 4th invention, it is possible to generate a sound iz′ft that rotates concentrically around the tailed person by ω n. Consider the multi-dimensional threedimensional transmission signal known as the 1-invention t-52 virtual matrix system according to the present invention, now at the position of the angle θ from the X thin of the reference 09-05-2019 1 point 0 at the intersection of X @ and Y axis. If a certain sound source t-8 (θ) is n, the sound source S (θ) can be expanded to Je-JeJ2θS (θ) = a @ 10 c, e + c−, e + cle. Here, *[email protected]=T.SIGMA., Cs = T4. IC'-t "" TT, smell = TQ, and further Tz = TH + T1. Every 'r, =' rkL-'rL. The applicant previously proposed that "EndPage: 1 Discrete 4 channel transmission is Ili]" by transmitting Tg, TL, TT, TQ, and called "universal matrix system".

In order to set the output signal of level S as G and the frequency of f as output signal H of level S as the output signal H of G as an output signal t-- leather as the output signal Hi, the function indication is given by the double signal line. If it is not, the output signal H at time t is. H: s, eJ (fs-fs) '27 rf, (, 431 G = 8 · · · · · · · · · · (7). Therefore, if the reciprocal difference between the output signals G and H is determined, then G + H-= 8-1 + 6-J (fs-fs) 2π "----(8) 曽 50-138801 (2) G-H-8 -1-e-J ('鳳 -f 鳳) 2 It becomes (9), and the rotation can be calculated by comparing the equations (2), (8) and (3) with the equation (9) Sound IJ! １ｔｔ−８（ｔ）とすｎば、こｎはＴＨ。 It will give a signal of TL. In the same writing 21. An output signal J having a level S having a frequency of −f, n is based on the output signal G, J = s, eJ (ft−fl) 2fft −−−−− Q. If the equation (4) is completely compared with the equation (4), the TT flaw signal for the sound source S (t) is given. Further, for the output signal of level S which has a frequency of 2f, -f, the output signal Gt-is based on n = S-, -J2Cf 1 -f *) 21 rt ..... If the equation IW (5) is compared with the equation +19, the output signal is given a TQ signal to the sound source S (t). As described above, it is understood that the 2-n channel rotational sound image can be dived using signals of different frequencies. An example of the implementation of the present invention will be described in detail with reference to FIG. (11, (5), (71 is frequency M variation 'A shooting aCVFO). (31 is an oscillator that generates a reference frequency (fl), and its output level is variable in frequency with a variable number of wave numbers (f'L, f2, f2 to be the same as 5), +41.
