A noise suppression device for an AM, FM, FM stereo, TV, video or motion picture receiver includes an input signal receiver, a field/disturbance information-detecting means for detecting a carrier level or the like of the input signal, a modulation information-detecting means for detecting the degree of modulation of the signal, a noise suppression control section, a noise data-generating means, and a noise cancel means. The device outputs a signal from which the noise is suppressed or cancelled. The advantage is a device which is less expensive to manufacture but provides better noise suppression than prior art devices.
