Design of FIR equalisers by sharpening identical subfilters
Paulo S. R. Diniz, J.C.E. Cabezas · IEE Proceedings G Circuits Devices and Systems · 1991
In the paper the design of FIR amplitude response equalisers employing the sharpening technique is proposed. These equalisers are useful in generating low-complexity FIR filters when applied in the prefilter-equaliser scheme. The paper also discusses the relationship between the sharpening of comb filters and well known interpolated FIR equalisers. A complete example is presented to illustrate the design procedure.
