2) Suppose that a continuous—time signal (CCU) (—00 < t < 00) is sampled every 0.5 seconds and yields the discrete-time signal cc[n] (n = . . . , —2, —1,0, 1, 2,. . .)
6 n = —1
2 n = 0
mlnl =
—1 n = 1 0 otherwise where the n = 0 sample corresponds to t = 0. Let 50,. (t) be the recovered continuous-time signal
when we apply sinc interpolation to x[n]. a) Write an equation for 22,.(13) that corresponds to the who] above.
b) Find $740.7).
c) Plot $7.05) over —2.2 S t S 2.2 using MATLAB. d) On top of your plot in part c, plot the samples x[n] obtained during —2.2 g t g 2.2 using the
relationship t 2 RT where T is the sampling period used to sample 93,305). Should the samples
:r[n] lie on the curve cc..(t)? Explain.
