The ordinary scope, > Hi,I really appreciate your kindness in replying me. * The transfer function gives the frequency response directly when Why do you do the FFT in chunks and splice the parts together? You expect a plot of the FFT to look like h(jw), but it doesn't.ĭo you convert the FFT from ? You find the discrete Fourier transform of those samples. You sample the impulse response and collect the samples. You excite it with an impulse the result is the impulse response. You start with the analog transfer function* h(s). > me.Thanking you in advance.Im using Matlab 7.0 > spectrum scope(FFT lenght=1024).Im expecting to get a graph like using the > block to buffer it and feed it into zero pad block and followed by FFT > discretize the signal.Then I buffer(buffer size=256 buffer oveerlap=64)

You seem to call 1/(s + 1) - surely you don't mean 1/s+1 = 1 + 1/s -Īn impulse response. > are the configuration?

Hi, I would like know how can I get frequency response from impulse
