Methods and systems for minimizing distortions in an analog data signal
include equalizing the analog data signal at a receive end. In an
embodiment, the invention adapts equalization parameters to a signal path
associated with the analog data signal. Adaptive control logic is
implemented with analog and/or digital components. In an embodiment, the
invention equalizes a discreet-time analog representation of an analog
data signal. In an embodiment, the invention digitally controls
equalization parameters. In an embodiment, a resultant equalized analog
data signal is digitized. In an example implementation, an analog data
signal is sampled, a quality of the samples is measured, and one or more
equalization parameters are adjusted with digital controls as needed to
minimize distortion of the samples. The equalized samples are then
digitized. The present invention is suitable for lower rate analog data
signals and multi-gigabit data rate analog signals.
