Design Trade-Offs for Linear-Phase FIR Decimation Filters and SD-Modulat ors
2006 (English)In: 14th European Signal Processing Conference,2006, Wien, Austria: EURASIP , 2006Conference paper (Refereed)
In this paper we examine the relation between signal-to-noise-ratio, oversampling ratio, transition bandwidth, and filter order for some commonly used sigma-delta-modulators and corresponding decimation filters. The decimation filters are equi-ripple finite impulse response filters and it is demonstrated that, for any given filter order, there exists an optimum choice of the stopband ripple and stopband edge which minimizes the signal-to-noise-ratio degradation.
