Abstract :
The authors present a non-traditional method of performing the decimation or interpolation required in an oversampled analog-to-digital conversion or digital-to-analog conversion. This technique uses a very efficient polyphase all-pass structure to perform the resampling task via a sequence of half-band filters. The arithmetic workload is reduced by a factor of five relative to the standard form of interpolation
