Abstract
A pulse generator for indicating a change in the magnitude of an input signal includes a comparator, a first network connected to one input of the comparator for receiving the input signal, and a second network connected to the other input of the comparator for receiving the input signal. Both the first and second networks provide output signals to the comparator which transition in response to a magnitude change of the input signal from their respective baseline magnitudes to respective peak magnitudes, and back to their respective baseline magnitudes. The component values of the networks are selected such that one of the first or second network output signals is positive relative to the other network output signal over some period of time during the transition to the peak magnitude and return to the baseline magnitude to cause the comparator to generate a pulse indicating a change in the magnitude of the input signal.
