In-Depth Information
Plot the desired and actual frequency responses for the following window-
ing functions:
a.
Rectangular
b.
Triangular
c.
Hanning
d.
Chebyshev (with sidelobe level of 30 dB below mainlobe)
In each case, record the following parameters in the actual frequency
response:
i.
Peak value of ripple (dB) in the passband
ii.
Transition bandwidth in Hz.
Exercise 4: Design of FIR and IIR filters using optimization techniques
Design the bandpass filter of order 7 given in Exericse 3 using the following
optimization methods:
a.
FIR realization using the Remez Algorithm
b.
IIR realization using the Yule-Walker Algorithm.
Plot the desired and actual frequency responses and in each case record
the following parameters in the actual frequency response:
i.
Peak value of ripple (dB) in the passband
ii.
Transition bandwidth in Hz.
