Inside Circuits
This circuit is a traditional summing amplifier configuration with the addition of the de clamping circuit. The operation is quite simple; each component-synchronization, color burst, picture information, etc.of the composite video signal is applied to its own input terminal of the amplifier. These signals combine algebraically and form the composite signal at the output.

The clamping circuit, if used, restores the 0-V reference of the composite signal.
