Dynamic equalization for partial response channels

Abstract From the Canadian patent

In a data recovery system comprising a receiver filter for match filtering and equalizing a signal received from a data transmission or storage channel and a combined dicode and partial response filter for automatic gain controlling and subsequent detection of the matched filtered equalized data signal and in response generating an output signal, the improvement comprising a combination of peak/power detector for detecting amplitude of the output signal and in response generating an amplitude/power output signal a, lowpass filter for filtering the amplitude/power output signal and in response generating a filtered output signal, an averager for averaging the amplitude/power output signal …
