Abstract
A signal processing circuit comprises a constant value generating circuit for generating a constant value (.alpha..sub.i) corresponding to a delay time (d.sub.i) for an input signal (V.sub.i (t)); an adding/subtracting circuit for alternately adding the constant value to the input signal and subtracting the constant value from the input signal for every half period of the input signal; and an amplitude correcting circuit for correcting an amplitude of an output signal of the adding/subtracting circuit for every half period of the input signal so that a delayed output signal (V.sub.o (t)) having a waveform corresponding to a waveform of the input signal is produced.
