In order to reduce a discontinuity resulting from noise cancellation in an output signal of a noise canceller, particularly in lower-frequency components, a compensator (10) for use in, for example, a radio receiver, comprises two amplifiers (21, 22) for amplifying an input signal in which one or more noise pulses may be superposed. One of the amplifier output signals is given a delay relative to the other. Supplied with a noise detection signal, gates (26, 27) interrupts the amplifier output signals to cancel the noise pulse that substantially simultaneously appears in the both signals. A combination of capacitors (31-33) superposes one of the noise-cancelled signal on the other during presence of the noise pulse to provide an output signal in which the discontinuity is compensated for.
