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 ...
You can apply an energy correction so that the sum is approximately 2 from 0 to Nyquist. 1-2 Deep Learning: Inverse continuous wavelet transform layer This release introduces the icwtLayer object, which computes the inverse continuous wavelet transform (ICWT) within a deep learning network. The ...
. That will eliminate your baseline drift and most of the noise, making it much easier for ...

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...
Open in MATLAB Online Ts = 1/100; t = -4:Ts:4-Ts; % Now looking to create the rectangular pulse fx = rectangularPulse(t,2); After this runs, it says invalid number of arguments. I also tried typing in 'rectpuls' because that's intially ...
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...

The nyquist plot now shows a contour comprised of both positive and negative frequencies. The arrows indicate the direction of increasing frequency for each branch. For complex-coefficient systems, the two branches are not symmetric. For real-coefficient systems, the negative branch is obtained by ...
