Abstract:
1. A method for operating an automatic gain control coupled to a variable gain amplifier, the automatic gain control being operable to control the variable gain amplifier in at least three modes of operation, the method comprising the steps of: a) operating the automatic gain control in a third mode of operation adapted for both said first signal modulation type and said second signal modulation type; b) comparing a first output level corresponding to said first signal modulation type to a second output level corresponding to said second signal modulation type; and c) transitioning the automatic gain control from said third mode to one of a first mode of operation adapted for said first signal modulation type and a second mode of operation adapted for said second signal modulation type responsive to said comparing step; wherein the variable gain amplifier is shared by both said first signal having the first signal modulation type and said second signal having the second signal modulation type in each of the at least three modes of operation comprising the first mode of operation adapted for said first signal modulation type, the second mode of operation adapted for said second signal modulation type, and the third mode of operation adapted for both said first signal modulation type and said second signal modulation type.
