An amplitude- and rise-time-insensitive timing-shaping filter (10) for converting a selected input signal into a bi-polar output signal having a zero-crossing point which is independent of the rise-time and amplitude of substantially linear-edge input signals, and which is amplitude insensitive for input signals of arbitrary fixed shapes. The amplitude- and rise-time-insensitive timing-shaping filter (10) includes an attenuator (14) for generating an attenuated signal, a delay path (12) for generating a delay signal, and a differencer (16) for subtracting the attenuated signal from the delayed signal. The delay path (12) of the present invention includes a low-pass filter of a selected order and configuration, an all-pass filter with a selected order and configuration, or an all-pass-low-pass filter combination for generating a delayed signal.
