The "right" way to do it when downsampling is to first apply an anti-aliasing filter and then decimate the signal but when upsampling, you first upsample and then apply interpolation (which can also be expressed as a filter). Various platforms provide functions to do just that (e.g. Python, MATLAB ). WebNov 20, 2024 · 4. Downsampling loses information. Upsampling is lossless when the factor is an integer (taken you also remember the factor), but some information is lost when the factor is not an integer. Upsampling could theoretically lose more information than downsampling, for very specific resampling factors. frilly adult dresses for doll costume
