For linear systems this can be achieved by a (possibly time-shifted) deconvolution, but we do not have the luxury of a convolution theorem for nonlinear systems. The infinite initial slope for {\beta <0} renders all techniques based on this useless. On the other hand, at least a ...
CNNs, or Convolutional Neural Networks, are models used in deep learning, especially for image and video tasks. CNNs use convolution operations to find spatial and temporal patterns in images. This helps them achieve high success in tasks like object recognition, face recognition, and handwriting ...
Since you know the convolution of a signal h(n) with shifted impulse will be shifted h(n) and then you add them . Oct 8, 2014 #5 rezeew 1,257 1 Your approach is on the right track, but there are a few things to consider. First, the unit step function u[n] is defined as...

If you come from a digital signal processing field or related area of mathematics, you may understand the convolution operation on a matrix as something different. Specifically, the filter (kernel) is flipped prior to being applied to the input. Technically, the convolution as described in the ...
While filtering the signal using convolution might help to find the fundamental frequency of 3KHz, it does not show if (and how) that frequency might change over time. However, spectral analysis should allow us to do just that. f, t, Sxx = cusignal.spectrogram(x, fs) ...
You can use interp1() to make the "step" sizes consistent. Just resample one of the signal so that the delta x between any two adjacent indices is the same as the other signal.Do
I do think arbitrary kernels computed dynamically might be possible with the sum table approach, which I hope to have a go at over the coming weeks - at least as a proof of concept. The idea is you turn each convolution into a series of summations which can be made much faster by cal...
