7. Consider the following signals f(t) = 4e-2tu(t) _ 2e-tu(t) v(t) = 2e-t/3 sin(5t)u(t) w(t) =...
Please answer the following fully with detailed
justification/explanation. Thank you.
Consider the signal e(t) (60m sin (50t) (a) Determine Xc(jw), the Fourier transform of e(t). Plot (and label) Xe(ju) b) What is the Nyquist rate for re(t)? (c) Consider processing the signal re(t) using the system shown below: Conversion to a Ideal to an e(t) y(t) impulse train Filter H-(ju) The sampling rate for this system is f DT filter is shown below 150 Hz. The frequency response of the...
