We find the Fourier series coefficients with our symbolic MATLAB function fourierseries. The corresponding magnitude and phase are then plotted using stem to obtain the line spectra. The magnitude and phase line spectra corresponding to y(t)=1+sin(100t) are shown in Fig. 4.3. □ Sign...
Fourier cosine and sine series of a function defined on [0, L ] are subsequently presented. Both traditional hand calculation and MATLAB are used to determine the Fourier coefficients. A MATLAB program is also given to compute and plot the partial sum of the Fourier series. Finally, the ...
A Fourier series separates a periodic function F(x) into a combination (infinite) of all basis functions cos(nx) and sin(nx).
