Abstract
An adaptive equalizer is implemented using digital feedback control and using jitter as the adjustment criteria. An adjustable transfer function is implemented to equalize an input signal to enhance the frequency response of the associated system. Jitter is determined for the filtered signal, and the frequency response of the transfer function is varied accordingly by applying a digital adjustment signal to the transfer function structure (for example, a lead-lag filter). The adaptive equalizer can thereby adapt to various transmission medium lengths and signal degradation levels.
