In case of Pattern1, the Zero-cross Detector Strobe occurs with the Zero-cross Detector

Function, and SW is switched. But in case of Pattern2, the Timer Function switches the

Analog SW after T=10msec, for the Audio Input Signal didn't cut the Signal Ground after

T=10msec which were set with the timer.
