Collective Filter Evaluation of an FSD Filter-Based Resampling Algorithm
Design How-To  
1/15/2002   Post a comment
Marek Blok of the Technical University of Gdansk, Poland, presents a collective filter for performance evaluation of a resampling algorithm based on fractional sample delay (FSD) filters. The proposed method is easy to use and lets you compare overall performance of the algorithm based on filters with different impulse response length or design methodology.
Decimation Stages with WDFs for Flexible Digital Receivers
Design How-To  
1/9/2002   Post a comment
Dieter Brckmann of the University of Wuppertal, Germany, describes a decimation filter architecture for highly optimized but flexible digital receivers. By using cascaded low-order wave digital filters for certain blocks, you reduce hardware cost and get superior sensitivity properties with respect to coefficient quantization effects, better noise performance, and less group-delay distortion.
