Signal processing circuit.

摘要

A signal processing circuit comprising a constant value generating circuit (23) for generating a constant value ( alpha i) corresponding to a delay time (di) for an input signal (Vi(t)); an adding/subtracting circuit (22) 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 (24) 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 (Vo(t)) having a waveform corresponding to a waveform of the input signal is produced.
