1. A method for implementing a flexible sampling-rate encoder, comprising the steps of:

  • (A) sampling an input signal at a regular time-interval to produce sampled data;

    (B) generating a pseudo-random bit sequence having a plurality of bits, wherein each bit corresponds to a different sampling time;

    (C) encoding a first set of said sampled data to generate an encoded stream when any bit in said pseudo-random bit sequence is equal to a first value and rejecting a second set of said sampled data when any bit in said pseudo-random bit sequence is equal to a second value, wherein each bit in said encoded stream corresponds to one of sampling times defined in step (B);

    (D) determining said different sampling time for each sample in said encoded stream; and

    (E) aligning said encoded stream with said pseudo-random bit sequence to determine said different sampling time for each sample in said encoded stream.
