Abstract
A selective call receiver (10) comprising a receiver circuit (100) having at least one radio frequency amplifier (112) and at least one mixer (114), a baud rate detector (102), a signal grader (104), and a gain controller (106). Coupling to the baud rate detector (102) to determine the signal quality of a selective call signal, the signal grader (104) collates the results of at least one baud rate detection with a plurality of predetermined criteria and assigns a signal grade to the selective call signal. The signal grader (104) then indicates the signal grade to the gain controller (106) which then sets the at least one radio frequency amplifier (112) and the at least one mixer (114) to operate with one of a plurality of selectable predetermined parameters including a gain setting and a mixer injection setting corresponding to the signal grade assigned to the selective call signal.
