Suppose we design a discrete-time filter using the impulse invariance technique with an ideal continuous-time lowpass filter
Question:
Suppose we design a discrete-time filter using the impulse invariance technique with an ideal continuous-time lowpass filter as a prototype. The prototype filter has a cutoff frequency of Ωc = 2π(1000) rad/s, and the impulse invariance transformation uses T = 0.2 ms. What is the cutoff frequency ωc for the resulting discrete-time filter?
