摘要
An apparatus for detecting leading pulse edges that can be used to delineate RF pulses, more specifically, for more accurately delineating the front and back of heavily modulated pulses, includes a controller (22), a lower hysteresis threshold comparator (26) and an upper hysteresis threshold comparator (24), a positive qualification timer (28) and a negative qualification timer (30). The controller (22) controls the timers to provide qualification times for the input signal above or below the hysteresis threshold levels in order to be able to validate a transition of a hysteresis threshold level as a pulse edge or not.
