<p>An FM receiver has a narrow pass band filter (1a), a wide pass band filter (1b), and a changeover switch (1c) for selecting one of the band filters. A noise canceler (4) is provided for detecting pulse noises included in a composite signal from a detector (3) and for producing a gating signal having a gating period for stopping the composite signal during the period. A receiving condition detector (8) detects receiving condition of the FM receiver and produces a pass band control signal for operating the changeover switch (1c) for selecting one of the pass band filters (1a; 1b). The receiving condition detector (8) applies the pass band control signal to the changeover switch (1c) to select the narrow pass band filter (1a) when a deterioration of the receiving condition is detected. Furthermore, the receiving condition detector (8) produces a gating period changing signal, and the noise canceler (4) responds to the gating period changing signal for changing the gating period. <MATH></p>
