AbshzctThe statistical analysis of coefficient quantization n o k io digital filters is a useful technique because it gives theoretid and practical results without resorting to lengthy case-by-case trials. The realization problem of digital filters can thus be simplified a n a l f i d y by statistical approaches. Furthermore, statistical approaches have an advantage of supplying unified tools for round-off and coefficient quantization noise.
