Matlab Project 2 Consider x(t): 2 -1 0.5 Choosing Fs-6 and K-22, plot the approximated signal using Fourier series. Re-plot the approximated signal choosing Fs-8 and K-22. Re plot the approximated signal choosing Fs 15 and K-22. Discuss the difference of three plots and try to find the reason. a. b. Choosing Fs-15, increase the K from 10 to 50 and investigate the effect of increasing the number of terms K.
