Design a flow chart based on this code:

clc; clear all close all Fs = 10; T = 1/Fs; L = 1000; t = (0:L-1)*T; phi1 = srrc_pulse(1, 1/10, 4, 0); figure plot(Fs*t(1:50), phi1(1:50)); NFFT = 2^nextpow2(L); Y = fft(phi1, NFFT)./L; Y2 = fftshift(fft(phi1, NFFT)./L); f = Fs/2*linspace(0,1,NFFT/2+1); f2 = ((0:NFFT-1) -ceil((NFFT-1)/2))/NFFT/T; figure plot(f, 2*abs(Y(1:NFFT/2+1))); figure plot(f2, 2*abs(Y2));
