In a receiver, what noise management circuit recognizes high-amplitude short-duration pulses and removes them?

A noise blanker is a specialized circuit in a receiver designed specifically to detect sharp, high-amplitude, short-duration pulses of electrical noise. Common sources of this noise include automotive ignition systems, lightning strikes, or certain types of electrical machinery. When the circuit detects one of these fast, loud noise spikes, it effectively turns off or "blanks" the receiver's intermediate frequency (IF) stage for a tiny fraction of a millisecond. This prevents the noise pulse from reaching the audio output and annoying the listener. Other noise management tools work differently. A noise limiter clips the maximum audio level but doesn't remove the pulse entirely, while narrowband filters restrict the audio frequency range. Automatic level control (ALC) is used to prevent transmitter overdrive, rather than reducing received impulse noise.
