Abstract

PURPOSE: To avoid the malfunction simply, by forming the clock signal higher in frequency than two types of selection control signals, and identifying and detecting each selection control signal with the output produced from the two decoders when the counter counts a given 2-clock pulse number.
CONSTITUTION: The clock signal higher than the selection control signal for the TV audio multiplex receivers of two types is produced at the oscillator 13, and this signal is introduced to the counter 18 and counting is made for a given time determined by the frequency of the selection control signal received. When the counter 18 counts the number of the first and second clock pulses predetermined, output is introduced from the decoders 21 and 22 of the first and second. Further, the presence of the output of the decoders 21 and 22 identifies and detects each selection control signal to avoid the malfunction simply.
