This function computes the n-dimensional discrete Fourier Transform over any axes in an M-dimensional array by means of the Fast Fourier Transform (FFT).By default, the transform is computed over the last two axes of … WebOct 8, 2024 · Clean waves mixed with noise, by Andrew Zhu. If I hide the colors in the chart, we can barely separate the noise out of the clean data. Fourier Transform can help here, all we need to do is transform the data to another perspective, from the time view (x-axis) to the frequency view (the x-axis will be the wave frequencies).
