Abstract
A quadrature detector quadrature-detects an FM signal. A first reducer and a second reducer reduce a direct current component included in the FM signal quadrature-detected in the quadrature detector. An FM detector generates a detection signal by FM detecting the FM signal in which the direct current component has been reduced by the first reducer and the second reducer. The offset unit adds an offset to the detection signal generated in the FM detector. An AFC unit generates a control signal for controlling the frequency of a local oscillation signal used in the quadrature detector on the basis of the detection signal to which the offset has been added by the offset unit and feeds back the control signal to a local oscillator that should output the local oscillation signal.
