Abstract
In a radio receiver, noise limiter apparatus specifically designed to clip impulse noise and to pass the audio signal undistorted up to about 80% carrier modulation. The noise limiter comprises a clipping circuit which is normally turned on by the audio signal to pass same, and a noise impulse amplifier branch containing an amplifier which is edgetriggered to cause clipping during the presence of noise impulses and to eliminate an output from the impulse amplifier when an audio signal is present.
