3. Matlab m-file code writing problem. You are given signal x(t) - exp(-2t) * sin (2t) a. Find amplitude of signal x(t) at t =0 and t = b. Find frequency and period of this signal c. You want to plot x(t) vs. t for t ranging from O to 10 sec with 0.01 second increment. Write a Matlab codes in editor to generate t vector and corresponding x vector and plot (t vs. x), We want to put the range of x axis O to 12, lab el Time (secl' and the range of y axis -2 to 2 and label x(t)'.
