PURPOSE:To realize an input of analog signals as well as a superposition integral operation, by providing a square root circuit that performs the square compression of signals plus a voltage adding circuit and a band-pass filter. CONSTITUTION:This device has an input terminal for AC and DC respectively so that an input is possible although the two signals to perform the integration of superposition are either of an analog AC signal and ananalog DC signal. The DC signals which are applied to DC input terminals (a) and (b) are directly supplied to square root circuit 13a and 13b to receive the square compression. On the other hand, the AC signals applied to AC input terminals (a) and (b) are supplied to offset voltage adding circuits 16a and 16b which add the DC bias voltage to convert an AC signal into a DC signal. The outputs of the circuits 16a and 16b are sent to a band-pass filter 15 after amplification. In such constitution, both the AC and DC analog signals are supplied to ensure the integration of superposition. |
