Abstract

PURPOSE: To detect the existence of cue tone signals by providing circuit for counting the number of repetitions of the cue tone signals.
CONSTITUTION: When a counting circuit 5 counts the third pulse of cue tone singals, the output of a first decoder 6 takes a value of 1. As a result, a flip-flop 8 is set. Upon reception if the subsequent tape running speed signals, the counting ciucuit 5 counts the fourth pulse of the cue tone signals so that the output of a second decoder 7 does not reach the logic level 1. As a result, the flip-flop 8 is not reset so that the output Q is held at 1. Consequently, the output of an AND circuit 14 takes a value 1 so that the cue tone signal detecting signals are generated at an output terminal 15
