Television receiver with automatic gain control (AGC)

A receiver comprising:

• a processing path having an input for receiving an input signal, and an output for providing an output signal;
• a power detector having an input coupled to a node of said processing path, and an output;
• and
• an analog-to-digital converter having an input coupled to said output of said power detector, and an output for providing a digital representation of said output of said power detector.

A method of performing automatic gain control comprising the steps of:

• receiving an input signal;
• processing said input signal to provide an output signal and thereby forming intermediate signals;
• detecting a power in a plurality of said intermediate signals;
• adjusting a gain of at least one controllable gain element in response to said step of detecting said power in said plurality of said intermediate signals.
