Problem $2,$ continuous$-$time sequences. $($Recommended time: $15$ minutes$)$

Generate and plot on the same figure each of the following continuous$-$time signals over

the indicated interval. On the plots show time on the horizontal axis, magnitude on the

vertical axis, and the titles of the axes and of the plots.

$x_a(t)=2sin(2000t+\frac{3}{2}),$ over the interval $0,0\mathrm{.}002$ seconds, and use the

sampling frequency $F_s=100kHz.$

$y_a(t)=2e^{-5t}(t),$ over the interval $-1,1$ seconds, and use the sampling

frequency $F_s=100Hz.$ is the unit step function$)$

You are requested to do the work on the command window of Octave. When you finish,

please raise your hand for the instructor to check your work and your plots. Write your

codes and paste your figure in the blank spaces below.
