Exercise 4. Computing and displaying the Fourier Transform of a signal Later in the semester it will become useful to determine the frequency response of a signal or system by taking the Fourier Transform empirically (rather than computing it analytically). To do so we make use of the fft and fftshift commands. The fft command is an efficient implementation of the Discrete Fourier Transform (DFT) known as the Fast Fourier Transform (FFT). When the FFT is computed the samples are...

please code on MATHLAB and show graph thank you in advance!
Generate the following function y1(t)=2* sin (2*pi* 1 *t)+4*sin(2*pi*2*t)+3*sin(2*pi*4*t) y2(t)=2*cos(2*pi*1*t)+4*cos(2*pi*2*t)+3*cos(2*pi*4*t) First, required by sampling theorem, the step size of t (delta t) has to be smaller than a value. Figure out this value and set the delta t at least 3 times smaller than this value and calculated y1(t) and y2(t). Increase the step size (delta t) and recalculate y1(t) and y2(t). See the difference. Calculate Fourier Transform of...

This is a MATLAB Question. Below is my base code for a Fourier
Series of a half triangle wave.
So I am being asked to isolate the first 8 components so that
only those first 8 components of the half triangle function are
calculated by MATLAB fft function, and then afterwards I am asked
to do the same thing but with the first 20 components rather than
the first 8. How do I isolate the first x number of components...

hello, I need help on solving the extra cradits.
i just need the screen shot if the code in MATHLAB with the
plot regenerating the original signal using FT result.
pls make it simple and clear. if you dont know the answer dont
replay.
thats my lab report page that i need to fill for the question
so you can have a better picture on what you are working on.
thank you so much
