MATLAB: Remove noisy channels out of an array


How to remove few noisy channels out of 64 channels?

Best Answer

  • Assuming that you are trying to remove signals with high noise from a group of channels. You can use the snr function in MATLAB to calculate the Signal-to-Noise ratio for all the channels. This will help you decide and remove the channels that are high in noise.
    If you just want noise reduction, then I suggest that you refer to the MATLAB documentation on Signal Smoothing.
