Abstract :
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 authors also discuss the relationship between the sharpening of comb filters and well known interpolated FIR equalisers. A complete example is presented to illustrate the design procedure
