How to plot a square wave Fourier series in Matlab?
A MATLAB code is used to plot the square wave function along with the Fourier sine series in order to compare the accuracy and error between the approximation and the actual function. sum = sum + 4/pi*sin(j*pi*x)/j; end plot(x, sum, 'r') hold on plot(x,f,'LineWidth',2) hold on error = abs(sum-F) Plot(x, error);
What is the Fourier series expansion for high frequency square wave ?`?
The Fourier series expansion of a square wave is indeed the sum of sines with odd-integer multiplies of the fundamental frequency. So, responding to your comment, a 1 kHz square wave doest not include a component at 999 Hz, but only odd harmonics of 1 kHz.
What is Fourier series in waves?
Fourier series is used to describe a periodic signal in terms of cosine and sine waves. In other other words, it allows us to model any arbitrary periodic signal with a combination of sines and cosines.
