Chapter7 LTI Discrete-Time
Systems in the Transform Domain
Transfer Function Classification
Types of Linear-Phase Transfer Functions
Simple Digital Filters
1
Types of Transfer Functions
The time-domain classification of a digital
transfer function based on the length of its
impulse response sequence:
- Finite impulse response (FIR) transfer
function.
- Infinite impulse response (IIR) transfer
function.
2
Types of Transfer Functions
In the case of digital transfer functions
with frequency-selective frequency
responses, there are two types of
classifications:
(1) Classification based on the shape of the
magnitude function |H(e
i
)|.
(2) Classification based on the form of the
phase function θ().

7.1.1 Digital Filters with Ideal
Magnitude Responses
A digital filter designed to pass signal
components of certain frequencies
without distortion should have a
frequency response equal to 1 at these
frequencies, and should have a frequency
response equal to 0 at all other
frequencies.
