    • A receiver capable of removing multipass distortion and improving an S/N. The receiver of the invention comprises a multipass removal filter for removing the multipass distortion from an intermediate frequency signal digitized by an A/D converter, an FM detector for detecting a desired signal outputted from the multipass removal filter, a mute processor and a high frequency removal filter as well as a stereo demodulator which are provided for processing a composite signal outputted from the FM detector and demodulating the same into left-right channel signals. The receiver further comprises a first field strength detector for detecting a first field strength from the intermediate frequency signal, a second field strength detector for detecting a second field strength from the desired signal, and a noise amount detector for detecting a noise component of the second field strength. A controller operates to perform a mute control on the mute processor, a high-cut control on the high frequency removal filter, and a separation control on the stereo demodulator, in response to the changes of the first field strength and the noise component.
