Patent ID: 8126088

Claim:
An apparatus for demodulating a signal, comprising: a signal preconditioner configured to receive a preconditioner input signal and to provide a preconditioner output signal based on a filtration of the preconditioner input signal into a filter output signal and a comparison of the filter output signal to one or more preconditioner references; and a demodulator configured to receive the preconditioner output signal and to provide a demodulator output signal by demodulating the preconditioner output signal, the demodulator including a phase frequency detector configured to provide the demodulator output signal based on a difference between a phase lock loop (PLL) input signal and a clock feedback signal, wherein the PLL input signal is based on the preconditioner output signal and the clock feedback signal is based on a generated clock signal; and a clock generator configured to generate the generated clock signal based on the demodulator output signal.
