The function calculates envelopes of the input signals as cosine-tapered envelope of the Hilbert-transformed signal. The signal should be detrended and/or the mean should be removed before processing.

Usage

signal_envelope(data, p = 0)

Value

Examples

## load example data set
data(rockfall)

## detrend data set
rockfall_detrend <- signal_detrend(data = rockfall_eseis)

## calculate envelope
rockfall_envelope <- signal_envelope(data = rockfall_detrend)

## plot envelope
plot_signal(data = rockfall_envelope)
