I am not sure how to apply low-pass and high-pass filters on a jpg image. The filters are calculated by: function[cL,cH]=getfilters(radius)[x,y] =meshgrid(-128:127,-128:127); z =sqrt(x.^2+y.^2); cL = z < radius; cH = ~cL;end so to filter the image...
This is a guide to Matlab fft(). Here we discuss the introduction to Matlab fft(), how fft() works along with respective examples. You may also have a look at the following articles to learn more – Low Pass Filter Matlab Matlab Sine Wave Simplify Matlab Matlab loglog()...

This filter is a five-stage multirate lowpass filter. Transform it to a bandpass filter by performing a frequency shift on the coefficients of each stage, while taking the cumulative decimation factor into account. Get Mn = 1; % Cumulative decimation factor entring stage n for ns=1:D_mul...

Meanwhile its result which we can get the data from figures and tables in the paper also shows that the smooth function as a low-pass filter can effectively filter out noise and keep the feeder current fundamental wave using the way that changes span values and method, but it will cause ...
According to the literature, the frequencies for velocity should be around 2-10Hz and not this high. I know that it is possible to use a Low-Pass filter on the data, but I cannot just cut off all frequencies higher than 20Hz, can I?
