ABSTRACT:
A modem receiver having a timing recovery circuit is disclosed. The timing recovery circuit includes circuitry for extracting timing information, multiplication circuitry responsive to the timing information for providing a clock envelope signal and processing circuitry for controlling the gain of the clock envelope signal as a function of the average power of the clock envelope signal.
