WebDigital filtering is a data treatment method that enhances the signal-to-noise ratio of an analytical signal through the convolution of a data set with an appropriate filter. This treatment method is another smoothing technique. If the filter is unweighted, it will perform in a similar manner to the boxcar filter. That is, it filters out ...
