Clamp, clamping

A&V
The circuit or process that restores the dc component of a signal. A video clamp circuit, usually triggered by horizontal synchronizing pulses, re-establishes a fixed dc reference level for the video signal. Some clamp circuits clamp sync tip to a fixed level, and others clamp back porch (blanking) to a fixed level. A major benefit of a clarnp is the removal of low-frequency interference, especially power-line hum.
