Latch Conditions

Pattern 1

Zero-cross Detector Strobe

(Form signal from insaide IC)

Audio Signal

SW Changing

Pattern 2

Zero-cross Detector Strobe

(Form signal from inside IC)

Audio Signal

SW Changing

In case of Pattern 1, the Zero-cross Detector Strobe occurs with the Zero-cross Detector Function, and SW is switched.

But in case of Pattern 2, the Timer Function switches the Analog SW after T = 10 ms, for the Audio Input Signal didn't

cut the Signal Ground after T = 10 ms which were set with the timer.

Timer Setting Time setting for Frequency band of Input Audio Signal.
