ABSTRACT:
A slice circuit for a data signal includes a clamp for clamping the data signal and a comparator having a first input coupled to the clamp, a second input coupled to a filter and an output coupled to a D/A converter. The output of the D/A converter is coupled to the filter such that a pulse width modulated signal is developed in the comparator output which is converted to a DC voltage by the D/A converter and filter for controlling the data slice level. The pulse width modulated signal is the sliced data.
