We wish to design a discrete-time lowpass filter using the bilinear transformation on a continuous-time ideal lowpass filter. Assume that the continuous-time prototype filter has cutoff frequencyΩc = 2π(2000)rad/s, and we choose the bilinear transformation parameter T = 0.4 ms. What is the cutoff frequency ωc for the resulting discrete-time filter?
