Digital decimation and compensation filter system |
摘要 |
This invention is for a multi-stage digital decimation filter, which includes a sinc6 filter, a half-band linear phase FIR filter and a symmetric, linear phase, FIR filter and a digital compensation filter. The multi-stage decimation filter down-samples the output of a sigma-delta modulator by a factor of about 64. The compensation filter provides compensation for rolloff introduced by the multi-stage decimation filter.
