ABSTRACT OF THE DISCLOSURE A delay circuit, which comprises a modulator for effecting contour modulation of signal using a signal from a carrier oscillator as a carrier, a delay for delaying the modulation output of the modulator, a variable phase shifter for phase shifting the carrier oscillator output signal, a demodulator for effecting demodulation by synchronous detection using the output of the variable phase shifter as a synchronizing signal, an adder for superimposing a reference signal on a first demodulation of signal from the demodulator corresponding to a first input signal to the modulator and supplying the resultant signal as a second input signal to the modulator, and a control for controlling the amount of phase shift by the variable phase shifter according to the reference signal demodulated by the demodulator, wherein the demodulator produces a first demodulated signal delayed behind the first input signal supplied to the modulator by an amount provided by the delay and a second demodulated signal delayed behind the first input signal by double the amount.
