METHOD AND APPARATUS FOR IDENTIFYING SIGNALING CHANNEL |
摘要 |
A receiver (100) has a channel scan mode of operation and a communication mode of operation. In the channel mode of operation, the passband of a filter (145, 144) is narrowed relative to the passband of the filter in the communication mode. According to another aspect of the circuit, a local oscillator (112, 142, 157) is selectively phase locked to an internal clock (137) during channel scanning and locked to the incoming signal during a communication mode operation.
