filters/MeanFilter

MeanFilter

The MeanFilter calculates the output for $$N$$ one-dimensional digital filters. Where the input, $$x$$ , is a ( $$N$$ x 1) vector of inputs and the output, $$y$$ , is a ( $$N$$ x 1) vector of outputs. The filter is described by number of observations, $$obs$$ , and implemented using the standard difference equation:

$$y[n] = (x[n] + x[n-1] + ... + x[n-obs])/obs$$
