Abstract :
A computer analysis shows that under the influence of interfering signals, the stereophonic vibration angle is up to ±25° in the Motorola system. The stereophonic images show `left´ and `right´ swing after the interference. The vibrating angle is smaller in the Kahn system. Generally, it is below ±5°. However, there are vibrations in both L and R signals so that the stereophonic image appears to undergo back and forth displacement
