Claim Text:
1. An FM receiver comprising: a quadrature detection device that quadrature-detects an FM signal; a reducer that reduces a direct current component included in the FM signal quadrature-detected in the quadrature detection device; an FM detector that generates a detection signal by FM detecting the FM signal in which the direct current component has been reduced by the reducer; an offset unit that adds an offset to the detection signal generated by the FM detector; and an Automatic Frequency Control (AFC) unit that generates a control signal for controlling the frequency of a local oscillation signal used in the quadrature detection device 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.
