Chapter 10, Problem #4

An analog pulse x(t) = u(t) ˆ’ u(t ˆ’ 1) is sampled using a sampling period T

_{s}= 0.1.(a) Obtain the discrete-time signal x(nT_{s}) = x(t)|_{t=nTs} and plot it as a function of nT_{s}

(b) If the sampled signal is represented as an analog signal as

determine the value of N in the above equation. Compute the Laplace transform of the sampled signal. i.e., X_{s}(s) = L[x_{s}(t]

(c) Determine the Z-transform of x(nT_{s}) or X(z). Indicate how to transform X_{s}(s) into X(z).
