Consider the following continuous-time sinusoidal signal:
x. (1) = sin(27Ft), -∞<i<∞
Since xal(t) is described mathematically, its sampled version can be described by values every T
seconds. The sampled signal is described by the formula:
F.
x[n] = x, (nT)= sin 27n
F.
-00 <n<0
Where F, = 1/T is the sampling frequency.
(a) Plot the signal x[n], 0 <n < 99 for F,= 5 kHz and F, = 0.5, 2, 3, and 4.5 kHz. Explain the

similarities and differences among the various plots.
