Consider the following Laplace transfer function:
(a) Determine H(z) and the difference equation using the impulse invariant method if the
sampling rate fs¼10 Hz.
(b) Use MATLAB to plot the magnitude frequency response jH(f )j and the phase frequency
response ϕ(f ) with respect to H(s) for the frequency range from 0 to fs/2 Hz;
(c) Use MATLAB to plot the magnitude frequency response jH(ejΩ)j¼jH(e
j2πfT)j and the phase
frequency response ϕ(f ) with respect to H(z) for the frequency range from 0 to fs/2Hz.
