DifferentiatorFilter

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

DifferentiatorFilter[data,ωc,n] uses a filter kernel of length n.

DifferentiatorFilter[data,ωc,n,wfun] applies a smoothing window wfun to the filter kernel.

Examples

Apply a differentiator filter to data:

data = Table[Sin[x], {x, 0, 2 Pi, 0.1}];
DifferentiatorFilter[data, 0.5]

Use a specific kernel length:

DifferentiatorFilter[data, 0.5, 21]
