Abstract: |
This Research Paper first, briefly explains Z-transform,
compares it with Laplace transform and also briefly explains
difference equation and differential equation.it then takes up
difference equation and demystifies its implementation in
digital filtering operations. This work further x-rays digital
filters with focus on finite impulse response (FIR) and
Infinite impulse Response (IIR) filter, basic comparison
between IIR and FIR are also highlighted.
Finally, based on this work, choice of a filter for a particular
purpose is hinted. However, this work does not go into
mathematical derivations but it did use the relevant formulae
and equations as it pertains to digital signal processing and
viewed from relevant application perspectives.
Keywords: Z-transform, difference equation, Finite
Impulse Response (FIR), Infinite Impulse Response (IIR). |
