4. Using the Fourier series coefficients {ak} obtained, construct the following signal N(t)>akekwot k=-N where ak is the kth Fourier series coefficients of r(t). Therefore, N(t) is the so-called 2N-term approximation of original signal r(t). In one figure, plot âN(t) versus t, for N 10, 20, 30, 40. In the same plot, also plot original signal (t). Visually compare N(t) and r(t) in the figure and comment on your observations

Use MATLAB to solve this question: Lab Exercises: Fourier Series Coefficients 4 In this lab, the objective is to create a set of functions that will enable us to do the following 1. Evaluate the Fourier Series coefficients for the following periodic signal which is defined over one period to be rt)240sin (100nt) for 0ts 1/100 (6) The period is 1/100 seconds. This signal is called a full-wave rectified sinusoid, because it contains only the positive lobe of the sinusoidal...

Using the Fourier series analysis Equation 3 for the periodic function r(t) shown in Figure 2.1, determine both the DC coefficient ao and a general expression for the other Fourier series coefficients ak. Do this by hand, not in Matlab. Show all your work in your lab report. You can add these pages as hand-written pages, rather than typing them in to your lab report, if you prefer Hint 1: It will be easiest to integrate this function from...
