ABSTRACT:
An adaptive proportional integral control loop determines a ratio of the input sampling rate to the output sampling rate for use in asynchronous sample rate conversion. An input counter counts input samples and its output is sampled at the output sampling rate by a latch. The output of the latch is passed through a closed loop circuit comprising variable gain and integrator sections.
