Patent ID: 8050646

Claim:
A noise suppressing device which suppresses pulse noise included in a frequency-modulated signal at low electric field strength, said noise suppressing device comprising: a band-limiting unit configured to band-limit a composite signal to a band equal to or lower than a predetermined frequency so as to output an audio signal, the composite signal being obtained by demodulating an FM baseband signal; a pulse detecting unit configured to detect pulse noise in the audio signal outputted by said band-limiting unit; a pulse judging unit having the composite signal as an input, and configured to judge that a detection result of said pulse detecting unit is valid in the case where pulse noise is included in the composite signal at a position corresponding to the pulse noise detected in the audio signal; and a pulse suppressing unit configured to suppress the pulse noise detected in the audio signal, in the case where said pulse judging unit judges that the detection result of said pulse detecting unit is valid.
