eseis (version 0.5.0)

signal_spectrum: Calculate the spectrum of a time series

Description

The power spectral density estimate of the time series is calculated using different approaches.

Usage

signal_spectrum(data, dt, method = "periodogram", ...)

Arguments

data

eseis object, numeric vector or list of objects, data set to be processed.

dt

Numeric value, sampling period. If omitted, dt is set to 1/200. Only needed if data is no eseis object.

method

Character value, calculation method. One out of "periodogram" , "autoregressive" and "multitaper", default is "periodogram".

…

Additional arguments passed to the function. See spec.pgram, spec.ar, spec.mtm.

Value

Data frame with spectrum and frequency vector

Examples

# NOT RUN {
## load example data set
data(rockfall)

## calculate spectrum with standard setup
s <- signal_spectrum(data = rockfall_eseis)

## plot spectrum
plot_spectrum(data = s)

# }
