PURPOSE:To allow the amplitudes or frequencies of two analog signals to coincide with each other by comparing the peak values of the amplitudes of the analog signals stored in two analog dynamic memories and regulating an amplification attenuation rate or circulation speed. CONSTITUTION:The outputs of the 1st analog dynamic memory ADM 1 and the 2nd ADM 2 are impressed to the two inputs of a voltage comparator circuit 3. The output of the circuit 3 is inputted to a gain control circuit 4 and the gain and attenuation rate of a variable amplifier 5 inserted into a closed loop of the ADM 2 is adjusted. Then, the loop gain of the ADM 2 is adjusted and the amplitude of the signal stored in the ADM 2 is so regulated that the level of this signal coincides with the signal level of the loop of the ADM 2. The amplitudes of the analog signals stored in the two ADMs are made to coincide with each other in this way and the preprocessing for determining whether the two analog signals are intrinsically the same or not is attained.
