How to plot FFT output in MATLAB?
Y = fft(X); Compute the single-sided amplitude spectrum of the signal. f = Fs*(0:(L-1)/2)/L; P2 = abs(Y/L); P1 = P2(1:(L+1)/2); P1(2:end) = 2*P1(2:end); In the frequency domain, plot the single-sided spectrum.
How to implement FFT in MATLAB?
Y = fft( X , n ) returns the n -point DFT. If no value is specified, Y is the same size as X . If X is a vector and the length of X is less than n , then X is padded with trailing zeros to length n . If X is a vector and the length of X is greater than n , then X is truncated to length n .
How do you plot a frequency plot in MATLAB?
plot(f,abs(X)/N); xlabel('Frequency (in hertz)'); title('Magnitude Response');
