ABSTRACT:
The concept of integer ratio sample rate conversion is extended to being a constant. This methodology allows sample rate conversion for all synchronous rates, where all rates are derived from the same crystal oscillator. For the implementation, the value of N/D is accumulated and depending on the overflow condition, either M or M+1 is selected as sample rate ratio for the conversion of each sample.
