Abstract
The present invention comprises a sample rate conversion system for eliminating sample rate slippage. The system of the present invention includes a first sample rate conversion circuit and a second sample rate conversion circuit. The first sample rate conversion circuit is adapted to multiply a sample rate frequency by a factor 'N', producing a first converted sample rate frequency. The a second sample rate conversion circuit is adapted to divide the first converted sample rate frequency by a factor of 'M', producing a second converted sample rate frequency. The sample rate frequency is used to encode an input signal, producing an encoded signal. The second converted sample rate frequency is used to decode the encoded signal, producing an output signal. The second converted sample rate frequency and the values of N and M are adjusted such that the input signal is substantially the same as the output signal, eliminating sample rate slippage.
