(a) Loads the .mat file and computes the Fourier transform of the phase.(b) Estimates the breathing rate (in breaths per minute) by finding the peak of the magnitudespectrum (not counting the high peak at the frequency of 0 Hz). Note that while you will clearlysee a peak visually, you are required to write MATLAB code that finds it.(c) Filters/nulls out all frequency components outside of the interval [0.1, 1] Hz (while leaving thefrequency content inside this interval unchanged) and plots the resulting filtered time-domainsignal.
All 3 parts please.

Matlab Program for Fourier Transforms: The function in MATLAB uses the Fast Fourier Transform algorithm to compute the Fourier transform of the data. Consider a sinusoidal signal 'x' that is a function of time 't' with frequency components of 15 Hz and the 20 Hz. Use a time vector sampled in an increments of 1/50 of a second over a period for 10 seconds. Ts =...
