nollmedelvärde
Nollmedelvärde, often translated as zero-mean or zero-average, is a statistical and signal processing concept referring to a signal or a set of data whose average value is zero. This means that over a given period or across a dataset, the sum of the positive values is equal to the sum of the negative values, resulting in a net average of zero.
Signals with a zero-mean property are common in various scientific and engineering disciplines. For instance, in
Achieving a zero-mean signal often involves a pre-processing step called DC offset removal or mean subtraction.
