fftcreate: Create a Fast Fourier transformed vector

In mrzdcmps/changeofevidence: Change of Evidence

Create a Fast Fourier transformed vector

Description

This function converts input signals into its Fast Fourier transform (FFT).

Usage

fftcreate(data)

Arguments

data	A seqbf object or vector to be transformed.

Details

The FFT shows the spectral density of the input. It can be understood as a harmonic analysis and indicates the strength of osciallative components comprising the signal. It can therefore be used to assess the meaning of oscillation as a characteristic. N/2 Frequencies are used as sampling rate.

Examples

density.bf <- fftcreate(seqbf)
tblFFT <- data.frame(density.bf = fftcreate(tbl$bf), density.rw = fftcreate(tbl$rw))
