Question
Transcribed Image Text:Signals x (t), h(t), and g(t) are given as follows:
x(t) = −2²
h(t)
=-2 sin(3t)
πt
=
-6-
-ej6t
sin(3t)
πt
=
-e¹³t
g(t)
- sin(3t)
1) Find the Fourier Transform of y(t), where y(t) = x(t) × h(t) + g(t).
2) What is the optimal rate at which you would sample the signal y(t) to avoid any aliasing?
3) Draw the sampled waveform in the frequency domain if you sample y(t) at your suggested
sampling rate in Part 2)?
