Abstract:
A pulse generator for indicating a change in the magnitude of an input signal, including:a comparator having a first input, a second input, and an output; a first network having an input for receiving an input signal and an output connected to the comparator first input, the first network output providing an output signal having a baseline magnitude; and a second network having an input for receiving the input signal and an output connected to the comparator second input, the second network output providing an output signal having a baseline magnitude; wherein in response to an input signal magnitude change, both the first and second network output signals transition from their respective baseline magnitudes to respective peak magnitudes and back to their respective baseline magnitudes such that at some time before both network output signals return to their respective baseline magnitudes, the difference between the magnitude of the first network output signal and the first network baseline magnitude is less than the difference between the magnitude of the second network output signal and the second network baseline magnitude, and wherein the difference between the first network baseline and peak magnitudes is greater than the difference between the second network baseline and peak magnitudes, thereby causing the comparator to output a pulse indicating the input signal magnitude change.
