Question
Given an analog filter with the transfer function
H(s)= 1,000/(s+1,000)
convert it to the digital filter transfer function and difference equation using the BLT if the DSP system has a sampling period of T = 0.001 second.
3.
The normalized lowpass filter with a cutoff frequency of 1 rad/sec is given as
Hp (s)=1/(s+1)
a. Use Hp (s)and the BLT to obtain a corresponding IIR digital highpass filter with a cutoff frequency of 30 Hz, assuming a sampling rate of 200 Hz.
b. Use MATLAB to plot the magnitude and phase frequency responses of H(z).
6.
Design a first-order digit allowpass Butterworth filter with a cutoff frequency of 1.5kHz and a passband ripple of 3 dB at a sampling frequency of 8,000 Hz.
a. Determine the transfer function and difference equation.
b. Use MATLAB to plot the magnitude and phase frequency responses.
9.

a. Determine the transfer function and difference equation.
b. Use MATLAB to plot the magnitude and phase frequency responses.
