Linear Phase Low-Pass IIR Digital Differentiators
Mohamad Adnan Al-Alaoui, Senior Member, IEEE
Abstract--A novel approach to designing approximately
linear phase infinite-impulse-response (IIR) digital filters in the
passband region is introduced. The proposed approach yields
digital IIR filters whose numerators represent linear phase
finite-impulse-response (FIR) filters. As an example, low-pass IIR
differentiators are introduced. The range and high-frequency sup-
pression of the proposed low-pass differentiators are comparable
to those obtained by higher order FIR low-pass differentiators.
In addition, the differentiators exhibit almost linear phases in the
passband regions.
Index Terms--Al-Alaoui operator, analog filters, bilinear trans-
formation, digital differentiators, finite-impulse-response (FIR) fil-
ters, infinite-impulse-response (IIR) filters, linear phase, low-pass
digital differentiators.
