Digital filter design plays an important role in the digital signal processor (DSP) field. The two methods of designing a digital filter are infinite-impulse
The method is based on the design of flat digital allpole filters with complex coefficients. Depending on the parity of the allpole filter order the resulting
The method is based on the design of flat digital allpole filters with complex coefficients. Depending on the parity of the allpole filter order the resulting
IIR filter design primarily concentrates on the magnitude response of the filter and regards the phase response as secondary The most common design method for digital IIR filters is based on designing an analogue IIR filter and then converting it to an equivalent digital filter
Design of IIR Filters Reference: Sections 7 1 of Text A digital filter H(ej ) with infinite impulse response (IIR) can bedesigned by first transforming it into a prototype analog filter H(jW ) andthen design this analog filter using a standard procedure
