A receiver includes a band-pass filter that limits a passband of an IF (Intermediate Frequency) signal, an FSK detector that detects the IF signal passing through the band-pass filter to generate a detection signal, and a control block that controls a modulation sensitivity of the FSK detector and a pass bandwidth of the band-pass filter, in which the control block controls the modulation sensitivity of the FSK detector according to the pass bandwidth of the band-pass filter.
