Tapered DFT

Function to calculate the tapered DFT.

Usage
taperDFT(x, freq = 2 * pi * (1:length(x))/length(x), regularization.type = "1", p = 0.1)
Arguments
x

time series vector.

freq

frequency vector.

regularization.type

character. if "1": sum of the taper equals to n, if "2": square sum of the taper equals to n. Default is "1".

p

proprotion of taper.

Details

Tapered DFT. The default taper is a Tukey's (or Cosine-bell) taper.

Value

Complex valued tapered DFT vector.
