Abstract: Systems and methods for performing automatic frequency control are provided. Instead of relying on individual frequency tuners for each channel of a multi-channel receiver system, the present subject matter uses a single frequency tuner for receiving each channel of the multi-channel receiver system. A locked demodulator may be designated as a reference demodulator and frequency offset values associated with the reference demodulator may be applied to other demodulators of the multi-channel receiver. These frequency offset values may be used by individual demodulators of each channel for correcting corresponding frequency offsets.

Abstract: The invention includes a circuit for applying a transfer function to correct values of an input signal. The transfer function is approximated by piecewise-linear segments generated by a plurality of segment operators. An input line in the circuit receives the input signal. Window detectors determine a value of the input signal, and select one of the segment operators based on the value of the input signal. The selected segment operator applies a correction value to correct the value of the input signal. Each of the segment operators generates a different linear segment of the piecewise-linear segments. Each of the segment operators simultaneously generates a respective correction value responsive to the value of the input signal. In one embodiment, a multiplexer selects one of the respective correction values to correct the value of the input signal.

Abstract: A system and method for reducing signal-to-noise ratio in a multi-component analog signal during analog to digital conversion. The multi-component analog signal is made up of a plurality of separate analog signals, with each of the separate analog signals having separate amplitude levels. A reference gain control signal, corresponding to the largest amplitude component of the multi-component signal, is first determined. Next, the reference gain control signal is used to generate a gain control signal. The gain control signal is then used to adjust each component of the multi-component signal by a gain value. Finally, the gain adjusted signals are converted to corresponding digital signals.
