Question

I need help with what code to type in to get the results. I know how to load the data text and I don't know what N is. There are parts a, b, and c. 6.

The file Test1_P6_DATA.txt contains 500 samples taken at sampling frequency 10,000Hz from signal x(t).

a. Perform Fourier Transform to obtain a graph of the frequency spectra of the signal x(t)

Hint: Plot(fq(1:N/2), abs(X(1:N/2))*2/N)

b. Determine the amplitude and phase angle of each frequency component of the signal x(t): Frequency Amplitude Phase

c. Write an equation to express x(t) in terms of cosine functions.

Explanation / Answer

a)

b).amplitude =20V

phase angle=20 degress
