In response to the questions generated by my posting about resampling. We
oversample the input signal at a very high rate (we place samples in
between two regular samples). The larger total number of samples fills in
the gaps (interpolation process). Internally the sample rate becomes
3.2768 GHz. After this point, the signal is put through a variable low
pass filter to insure the correct aliaising limit is used. Finally the
signal is divided (decimation process) until the desired sample rate
established for the output signal. The large amount of oversampling
allows accurate operation over then entire audio frequency.
