Diode limiters or clippers in the audio portion of a receiver can typically remove sporadic, high-amplitude noise transients of short duration, such as impulse noise. The limiting or clipping threshold level is usually set just above the audio signal's maximum peak level. Another circuit alternative for mitigating the effects of high- amplitude noise pulses is a blanking circuit. A blanking circuit, in essence, detects a high-amplitude, short-duration noise spike and mutes the receiver by turning off a piece of the receiver for the duration of the pulse. The problem of limiter and blanker circuit is:
