Abstract
A finite impulse response (FIR) filter for implementing a Hilbert transform is provided. The FIR filter includes a plurality of programmable delay cells connected in cascade between an input terminal of the FIR filter and an output terminal of the FIR filter. Each programmable delay cell has associated therewith a constant filter coefficient and a programmable delay coefficient. The FIR filter is also applicable for processing signals originated by the reading of data from a magnetic storage media which employs perpendicular recording.
