A pulse filter circuit is configured to eliminate pulses that are less than a specified duration and pass those that are greater than the specified duration. A buffer receives a signal and applies the buffered signal to a resistance-capacitance charging-discharging circuit (e.g., RC filter). When the output of the RC filter has, in response to the buffered signal, charged or discharged, as appropriate, to cause the output of a slicer to change, logic circuitry controls switching circuitry to pull the output of the RC filter to be fully charged or discharged, respectively. In this manner, pulses that are too short to charge/discharge the RC filter enough to cross the threshold of the slicer do not reach the slicer circuit output, but pulses that are long enough to cross the slicer threshold are transmitted by the slicer.
