Apparatus and method for providing an agc function using multiple feedback sources

A method for providing an AGC function, comprising:

• using a tuner to generate one of first and second IF signals;
• generating a first AGC signal responsive to said first IF signal;
• generating a second AGC signal responsive to said second IF signal;
• generating a wide band third AGC signal responsive to at least one of said first and second IF signals;
• and
• using a switch to selectively provide one of said first, second and third AGC signals to said tuner responsive to a predetemined condition.

A television signal receiver, comprising:

• a tuner operative to generate first and second IF signals;
• a first demodulator operative to generate a first AGC signal responsive to said first IF signal;
• a second demodulator operative to generate a second AGC signal responsive to said second IF signal;
• a wide band AGC detector operative to generate a third AGC signal responsive to at least one of said first and second IF signals;
• and
• a switch operative to selectively provide one of said first, second and third AGC signals to said tuner responsive to a predetermined condition.
