Problem 1.

a) Plot 2*tri(t+1), 2*tri(-(t+1)), and 1.5*tri((t+1)/3) Confirm your answers with Example of time shifting and changing the width of continuous time signals

b) Let f(t) = rect(t/2) + rect((t - 2)/2)*Exp((-(t - 1))/.25), plot f(t).Confirm your answer with Example of flipping and time shifting continuous time signals.

c) Let f(t) = rect(t/2) + rect((t - 2)/2)*Exp((-(t - 1))/.25), plot f(-(t-b)) for b = -1.2. Confirm your answer with Example of flipping and time shifting continuous time signals.

d) Let f(t) = rect(t/2) + rect((t - 2)/2)*Exp((-(t - 1))/.25), plot f(-(t-b)) for b = 1.2. Confirm your answer with Example of flipping and time shifting continuous time signals.
