What are the realization methods in describing digital filters?
Realization involves converting a given transfer function, H(z), into a suitable filter structure that is generally depicted using block or flow diagrams and shows the computational procedure for implementing the digital filter.
What are the different types of structures for realization of IIR system?
STRUCTURES FOR IIR SYSTEMS: IIR Systems are represented in four different ways 1. Direct Form Structures Form I and Form II 2. Cascade Form Structure 3. Parallel Form Structure 4.
What are the steps to realize IIR filter using cascade structure?
Overall IIR system can be realized as cascade of two function H1(z) and H2(z). Here H1(z) represents zeros of H(z) and H2(z) represents all poles of H(z). 1. Direct form I realization of H(z) can be obtained by cascading the realization of H1(z) which is all zero system first and then H2(z) which is all pole system.
What are FIR & IIR filters explain their realization structures?
The crucial difference between FIR and IIR filters is that the FIR filter provides an impulse response of a finite period. As against IIR is a type of filter that generates impulse response of infinite duration for a dynamic system. Here we are talking about finite and infinite impulse response.
