I would like to know how to use the Signal Processing Toolbox to filter my data. …
I have observations of a noisy channel and i form a vector y of length n from those observations. I need to compute the autocorrelation matrix from this vector y which should be …
Hello, I have two sets of measurement data (sine wave of 10 = Hz and fs = 2048 Hz) with lots of noise. I tried to filter them using a butterworth lowpass filter using filtfilt func…
Any one help me how to downsample image in horizontal direction and vertical direction. i used downsample(image,4), it will down sample image in both the direction, but i need t…
