Abstract
An asynchronous sample rate converter prevents the folding back of a signal in the passband of an input sample rate into the passband of the output sample by adaptively controlling the decimation rate. The ASRC includes an adaptive decimation rate controller that selectably controls a decimation filter based on the ratio of the input sampling rate to the output sampling rate. By adaptively controlling the decimation rate in the ASRC, a significant amount of area and power is saved.
