WebApr 13, 2024 · We downsample by a factor of two means we use a sampling rate which is half of the original one, i.e. we discard every second sample. All frequencies higher than the new nyquist frequency can cause aliasing, therefore we filter them out by applying an appropriate low pass filter before downsampling. Correct so far? Apr 13, 2024 at 14:58 WebFiltering Before Downsampling. This example shows how to filter before downsampling to mitigate the distortion caused by aliasing. You can use decimate or resample to filter and downsample with one function. …
