plot((1:n),L3,'b',(1:4:n),L4,'r',(1:4:n),L5,'g'); legend('original','pick 1 of 4','downsampled factor 4'); but a random signal (white noise) which has constant energy from 0 to Nyquist frequency will give quite different outputs . This ...

Open in MATLAB Online Ran in: I think you meant to post this comment in StarStrider's answer. I can see a few problems, assuming that you're trying to approximate the CTFT. s and t must both be row vectors with the same number of elements...
Open in MATLAB Online I'm trying to transforming an already know signal from time domain to frequency domain using fftfunction in MATLAB. And I got different values of amplitude whenever I change the value(nfft) of length of signal. I'm therefore wondering if there is a rule to choose...
BTW: note that n is always 1000 in your case, so you can compute "period" outside the loop; further, as you have an offset of 350 now, a could start from 0; just be(0) is wrong syntax in Matlab because matrix indices start with 1.will...

However, the above formulation assumes that your data are even. I would go further and try to pad your time data with zeros to next power of 2 (i.e., above is 2^10). Let me know if you have questions about doing that.Depending...
Homework Statement Hi, I'm given a transfer function, and am suppose to draw Bode plot from it. H(s) = ( 2000s (s - 1) ) / (s + 2000)^2 I'm wondering...
Yet, when I plot the root locus in MATLAB I seem to have three branches? b)symmetry My textbook just says "the root locus is symmetrical about the real axis". This is true from the image but how can I show this mathematically? c)Starting and ending points again my ...
