Abstract

PURPOSE: To detect only a signal within a range without misdetection by making the signal detection frequency range constant.
CONSTITUTION: A slicer circuit 2 converts an input analog signal into a digital signal, the 1st counter circuit 3 decides the upper limit of a detected frequency, detects a frequency lower than the upper limit frequency and a monostable multivibrator circuit 4 decides the lower limit of the detected frequency and detects the frequency higher than the lower limit frequency. Then the 2nd counter circuit 5 generates an output only when the period of the output of the monostable multivibrator circuit 4 is longer than a prescribed period and acts like an on-guard timer. Thus, mis-detection of the signal is prevented.
