Abstract :
In the present paper, a number of bilinear digital ladder filters (BDLF) are analysed with respect to magnitude sensitivity, magnitude response with respect to coefficient quantization, stability, occurrence of limit cycles and quantization noise levels. The results are compared to wave digital filters (WDF), and cascade-form filters. It is found that BDLFs in most cases perform better than WDFs, while they at the same time have a simpler structure
