Wideband linear-phase FIR differentiators utilizing multirate and frequency-response masking techniques
Zaka Ullah Sheikh, Håkan Johansson · 2009
This paper introduces a structure for the realization of wide-band linear-phase finite-length impulse response (FIR) differentiators. It is based on multirate and frequency-response masking techniques. Examples show that this structure achieves computational savings between some 10% and 65% for bandwidths in the range between 0.9 pi and 0.98 pi in comparison with conventional linear-phase differentiators.
