Analysis of multirate interconnected discrete filter systems
Len T. Bruton, R.H. Khan · IEE Journal on Electronic Circuits and Systems · 1979
An exact analysis technique is presented for a class of multirate digital filters. The class of multirate filters considered can be modelled as an interconnection of uniform-rate subsystems, each operating at a different sampling rate. The method is particularly suitable for the analysis of a recently proposed multiplierless multirate digital filter structure. A multiplierless fifth-order lowpass ladder filter example-is given
