Abstract

PURPOSE:To make the response quick and to eliminate high frequency components from an output signal, by subjecting input signals to arithmetic processing to cancel their high frequency components by each other. CONSTITUTION:Signals U and V are not only inputted to a multiplier 1 and multiplied but also inputted to a multiplier 4 through differentiators 3-1 and 3-2. Thus, the multiplier operates UcosomegatXVcos(omegat-theta) to output a signal W2 of UV/2[costheta+cos(2omegat-theta)]. An adder 5 adds a signal W1=UV/2[costheta-cos (2omegat-theta)]and the signal W2=UV/2[costheta+cos(2omegat-theta)], and therefore, 2omega components are cancelled, and a signal W0=UVcostheta is derived.
