た２周波数判別回路。[Scope of Claim for Utility Model Registration] The input pulse signal is supplied to a monostable multivibrator whose inversion time is set so that there are no pulses at high frequencies above a certain level, and the output of this monostable multivibrator is DC-clamped and then averaged. A two-frequency discrimination circuit is provided with a means for converting the average value into a value, and uses a comparator to discriminate the average value.
