T = 3*(1/25); fs = 1000; t = 0:1/fs:T-1/fs; x = sawtooth(2*pi*25*t,1/2); x = (x + 1)*0.5; subplot(3,1,1) plot(t,x) grid on xlabel('Time t (sec)') ylabel('Amplitude')
This is my code and my signal. I want to find its fifth and seventh harmonics. How can I do that ? I cannot find any source or any example for this. Can anybody help me ?
