1) Given the waveform of x1 (t ) generate and plot the waveform of:
(a) x1(-2t)
(b) x1[-2(t - 1)]
2) Given the waveform of x(t) shown in P1.11(a), generate
and plot the waveform of: (a) x(2t+6)
*(b) x(-2t + 6) (c) x(-2t - 6)
3) Generate plots for each of the following step-function waveforms over the time span from -5 s to +5 s.
(a) x1(t) = -6u(t + 3) (b) x2(t) = 10u(t - 4)
(c) x3(t)=4u(t+2)-4u(t-2)

4) Generate plots for each of the following functions over the time span from -4 s to +4 s.
(a) x1(t) = 5r(t + 2) - 5r(t)
(b) x2(t) = 5r(t + 2) - 5r(t) - 10u(t)
*(c) x3(t)=10-5r(t+2)+5r(t)
