ABSTRACT:
In a phase digitizer for converting phase information of an analog signal into a digital representation, a phase accumulator stores incremental phase angle values of a reference signal. A trigger circuit which is responsive to an input signal and a sample signal generates a strobe signal which causes the incremental phase angle value stored in the phase accumulator to be transferred to a holding latch. The value of the holding latch is then transferred to an output latch which provides a digital representation of the phase angle of the input signal.
