Abstract:
A method for inspecting for baseline wander and compensating for baseline wander of a pulse, comprising the steps of:(a) after training mode has terminated, check the width of the pulse;(b) if the width of the pulse is greater than a predetermined value, initiate baseline wander mode and begin compensating for baseline wander;(c) freeze peak adjustment algorithm and equalization adjustment algorithm;(d) if the peak voltage of the high pulse is less than the voltage of a HIGH PEAK control signal, shift the waveform towards HIGH PEAK control signal, away from the direction of the common mode;(e) if the peak voltage of the high pulse crosses the voltage of a HIGH PEAK control signal, shift the waveform away from HIGH PEAK control signal, in the direction of the common mode;(f) if the peak voltage of the low pulse is greater than the voltage of a LOW PEAK control signal, shift the waveform towards LOW PEAK control signal, away from the direction of the common mode; and(g) if the peak voltage of the low pulse crosses the voltage of a LOW PEAK control signal, shift the waveform away from LOW PEAK control signal, in the direction of the common mode.
