Methods and apparatus of signal processing are described. In a method according to one embodiment, a high-frequency region of a digital signal is detected. In response to the detecting, the high-frequency content of the digitized signal is increased in at least a portion of that region.

Digital filter

A phase-locked loop wherein the output signal is effectively sampled at an increased rate from conventional phase-locked loops, allowing for a greater increase in the ratio of the output frequency to the input frequency while reducing the possibility of jitter or failure to lock. Multiple differently phased reference signals and correspondingly phased feedback signals are produced. The comparison of the feedback signals and the reference signals produce multiple error signals which are combined to adjust the oscillation frequency of the voltage-controlled oscillator.
