Can someone explain each part of this solution I don’t understand Example 1 square wave Derive the Fourier series (FS) representation of a square wave of period T with duty cycle τ-AT, where 0< B<1. The square wave is symmetrically defined over one period by a Heaviside unit-step function, as in Eq. (28) It! <汁 (77) The ordinary unit-step could also be used, but the Heaviside is more natural here because the FS representation will pass through the 1/2 point...

1. 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...
Use MATLAB to : ("j" is the imaginary number.) The term lo is the fundamental frequency of the periodic signal, 2/T, where T is the period. Frequencies nlo, where n is an integer, are the harmonics. This infinite sum is an exact representation of the original function. If we use a finite sum, where n goes from -N to N, we will get an approximation "X-(t)". In this problem we will calculate and plot the Fourier series representation of a...
