ABSTRACT:
An equalizer receives an analog input signal and filters the signal to undistort the input signal. A converter stage converts the analog input signal into a digital output signal for use in a digital system. A bit sequence indicator analyzes the structure of the digital output signal to determine whether any errors have occurred in transmission and conversion. An adaptor state machine causes the modification of the analog signal based on a feedback loop including information on the errors detected in the packets of digital signals, rather than the analog data itself.
