Explain Limit Signal Spectrum to Prevent Aliasing?
The sampling frequency should at least be two times that of the highest frequency in the incoming signal to avoid aliasing. This rate is generally known as the Nyquist limit.
Q. The response v(t) of a linear system to a unit-step excitation i(t) is given by v(t) = (5 - 3e -t + 2e -2t ) u(t). Determine the transfer function H(s) = V (s)/I (s).
