discrete fourier series matlab code
we get the coefficients for the discrete Fourier series (DFS) representation: (12.5.
9) F k = ∑ n = 0 N − 1 f n e − j 2 π k n N .
Notice that the sequence of coefficients { F k } is periodic with period N.
How to write FFT code in Matlab?
Y = fft(X,L,dim); Calculate the double-sided spectrum and single-sided spectrum of each signal.
P2 = abs(Y/L); P1 = P2(:,1:L/2+1); P1(:,2:end-1) = 2*P1(:,2:end-1); In the frequency domain, plot the single-sided amplitude spectrum for each row in a single figure.
