Abstract

A circuit for filtering narrow pulse and compensating wide pulse, including a signal shaping circuit, a filter circuit, and a pulse width compensating circuit. The signal shaping circuit processes an input signal and transmits the input signal to the filter circuit. The filter circuit filters off narrow pulses of the input signal. The pulse width compensating circuit compensates the wide pulses of the input signal and outputs an output signal.
