A validation circuit is coupled to the positive crossing sense circuit to validate a previous zero crossing and the positive crossing of the input voltage after the positive crossing of the of the input voltage has occurred. A measurement circuit is coupled to the positive crossing sense circuit and the validation circuit to count a time between positive crossing pulses of the input voltage.
