ABSTRACT:
A system for determining the fundamental frequency of a digitized AC signal is disclosed. Each signal zero crossing is detected, and in response to each zero crossing, two discrete impulses are generated. In response to the train of generated impulses, the system determines the fundamental frequency of the AC signal.
