Document Type and Number:
Japanese Patent JP2001525632
Kind Code:
A
Abstract:
A phase digitizer and method with error compensation is provided that utilizes recordings from a digitally generated phase reference to measure the relative time between events, such as, for example, between the input zero crossing and sample pulse events. The digital reference has a constant frequency which is equal to the desired signal frequency, and thus the phase of the reference can be used to measure the time between events. Consequently, by using the existing digitally generated phase reference, the hardware "costs" associated with implementing the prior phase digitizer error compensation approaches can be significantly reduced and/or eliminated.
