Using either T-filter or the Matlalb
Filter Designer app, design a filter based on the specifications below.
A. Sampling Frequency
16 kHz if your age is even
24 kHz if your age is odd
If your birthday is between November 25th and December 4nd, you 'll have to
B. Filter Type
Month of Birth
January, February, March
April, May, June
July, August, Spetember
October November December
For High Pass and Low Pass use Cutoff Frequency
f = ( 400 your + .25). * fs
Next to the last digit of cellphone number
For Bandpass and Bandstop, let fc be the center frequency and the total
width be 15 * fs
D. Transition Bands
For High Pass and Low Pass, let the transition band be .15 * fs
For Bandpass and Bandstop, let the each transition band be 1 * fs
E. Passband Ripple and Stopband Attenuation
The passband ripple should be less than 5 dB and the stopband attenuation
should be at least 40 dB.
Design several filters that meet these specifications using different length,
windows, etc. For each filter show the frequency response, phase response,
location of poles and zeros, and impusle response.
In your report, explain all your results and recommend one of your choices
to be implemented.
Illustrate the operation of your filter you believe should be implemented
by using the filter (b, a, x) function where x is a sine (or cosine) with fre-
quencies .13fs, 27fs, 32fs, and .4fs. Show that these results are reasonable.
These solutions may offer step-by-step problem-solving explanations or good writing examples that include modern styles of formatting and construction
of bibliographies out of text citations and references. Students may use these solutions for personal skill-building and practice.
