Abstract :
The suboptimal designing algorithm of spectrum shaping filter vs surface acoustic wave technology is discussed, After resampling at interval of M, the original weighting function is decomposed into two weighting functions with less order by the zero-separating of Z-transform, then represented by interpolation derived from the signal reconstruction theory, and can be further suboptimized using the standard Remez optimization method and realized by SAW filter with multistrip coupler. The simulation results for a Blackman shaping filter confirm that this algorithm is very simple and effective
