Write a program using Python$-$inspired pseudo$-$code to generate approximations of

each of the figures $($a$),($b$),$ and $($c$)$ that follow. The only things that you are told is

that each plotted array is $1024$ in length, that only the real part of the signal is

shown in each plot, and that the amplitude of the signal is $1\mathrm{.}0.$ You must generate

the sawtooth signal in your program. You can assume that a function plot$()$ that

takes an array as input is available to you to call. You can also assume that the

following standard scientific functions $($and other common scientific functions$)$ are

also available should you wish to use them: linspace, tile, fft$,$

fftshift, ifft, ifftshift, real $.$
