For the waveform given below:
1. (10 pts) Obtain its cosine/sine Fourier series representation and
a. (20 pts) By using this representation, plot its approximate waveform in MATLAB for 𝑁𝑁 =
{1,3,5,10,100} harmonics in addition to the DC term.
2. (10 pts) Convert the representation to amplitude/phase format
a. (20 pts) By using this format, plot its approximate waveform in MATLAB for 𝑁𝑁 = {1,3,5,10,100}
harmonics in addition to the DC term.
3. (20 pts) Convert the representation to the complex-exponential format
a. (20 pts) By using this format, plot its approximate waveform in MATLAB for 𝑁𝑁 = {1,3,5,10,100}
harmonics in addition to the DC term.
