Simple Noise Blanker Circuit Diagram

This is a Simple Noise Blanker Circuit Diagram. A noise blanker is a device that detects pulses and blocks the signal during the time of each pulse. This noise blanker takes a sample of IF input voltage, amplifies it, and drives a switch. The switch (when activated by a noise pulse) adds a heavy load to the first IF stage and kills the gain for the pulse duration.
