Abstract
Methods and systems for adaptively equalizing an analog information signal for a signal path, including sampling the analog information signal, thereby generating analog samples, and performing an equalizing process on the analog samples, wherein the equalizing includes processing an average of post-transition sample amplitudes and an average of steady state sample amplitudes of the analog samples to produce equalized analog samples.

A method for adaptively equalizing an analog information signal for a signal path, comprising:
- sampling the analog information signal, thereby generating analog samples;
- and
- performing an equalizing process on the analog samples, wherein the performing the equalizing process includes adjusting a difference between an average of post-transition sample amplitudes and an average of steady state sample amplitudes of the analog samples to produce equalized analog samples.
A method for processing time staggered portions of an analog information signal for a signal path, comprising:
- sampling the analog information signal at a plurality of phases;
- measuring an equalization quality of the samples from one of the plurality of phases;
- and
- equalizing the samples from each of the phases based on the measured equalization quality of the one phase, the equalizing including adjusting a difference between an average of post-transition sample amplitudes and an average of steady state sample amplitudes of the analog samples.
A system for processing a serial analog information signal, comprising:
- a sampler configured to sample the serial analog information signal to generate analog samples;
- an equalizer coupled to said sampler and configured to minimize inter-symbol interferences in the analog samples output from said sampler, said equalizer being configured to adjust a difference between an average of post-transition sample amplitudes and an average of steady state sample amplitudes of the analog samples to generate equalized samples;
- and
- a quantizer coupled to said equalizer and configured to quantize said equalized samples output from said equalizer.
