Problem 3 This problem involved creating a function called spectral_props that takes the input sample signal and time interval, and returns -6dB bandwidth center frequency and percentage the bandwidth
A.1 1) MATLAB CODE "spectrum function"
function [V] = spectrum1(f,fc,bw); A = sqrt(log(2)/(pi*bw); V = A*sqrt(pi)*(exp(-(4*pi^2*A^2*(f-fc).^2);
