2. The following MATLAB code can be used to plot the graph of a piecewise-continuous signal, \newline x(t), above.\newline >> step = 0.001; \newline >> t = 0:step:4; \newline >> x = (t>=0)+(t-2>=0)-2*(t-4>0); \newline >> plot (t,x); xlabel('t'); ylabel('x(t)'); \newline Modify the code to plot the graph of the following signals: \newline (a) $y(t) = \sum_{k=0}^{4} (\frac{1}{2})^{k+1} u(t-k)$, $-1 < t < 10$. \newline (b) $z(t) = \begin{cases} -t^2, & -\pi < t < 0 \\ t^2, & 0 < t < \pi \end{cases}$ and $z(t + 2\pi) = z(t)$ \newline Note: z(t) is periodic with period of 2?. To plot the graph containing three periods of z(t), \newline add the code below to generate three periods of z(t). \newline >> t_tilde = linspace (-3*pi, 3*pi, 3*length(t); \newline >> z_tilde = [z z z] % z represents 1 period of the signal \newline >> plot(t_tilde,z_tilde); xlabel('t'); ylabel('z(t)');
