HighpassFilter

HighpassFilter[data, ωc] applies a highpass filter with a cutoff frequency ωc to an array of data.

• HighpassFilter[data, ωc, n] uses a filter kernel of length n.
• HighpassFilter[data, ωc, n, wfun] applies a smoothing window wfun to the filter kernel.

Examples

HighpassFilter[RandomReal[1, 100], 0.1]

HighpassFilter[Table[Sin[t] + 0.5 Sin[10 t], {t, 0, 10, 0.01}], 0.3]
