signal_integrate function

Integrate a seismic signal

The function integrates a signal vector to convert values from velocity to displacement. Two methods are available

signal_integrate(data, dt, method = "fft", waterlevel = 10^-6)

Arguments

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

• dt: Numeric scalar, sampling rate.

• method: Character scalar, method used for integration. One out of "fft" (convert in the frequency domain) and "trapezoid"

  (integrate using the trapezoidal rule). Default is "fft".

• waterlevel: Numeric scalar, waterlevel value for frequency division, default is 10^-6. Only used when method = "fft".

Returns

Numeric vector or list of vectors, integrated signal.

Examples

## load example data set
data(rockfall)

## deconvolve signal
rockfall_decon <- signal_deconvolve(data = rockfall_eseis)
                                    
## integrate signal
rockfall_int <- signal_integrate(data = rockfall_decon)
                                 
## Note that usually the signal should be filtered prior to integration.
