signal_deconvolve {eseis} | R Documentation |
Deconvolve a signal vector.
Description
The function removes the instrument response from a signal vector.
Usage
signal_deconvolve(
data,
sensor = "TC120s",
logger = "Cube3BOB",
gain = 1,
use_metadata = FALSE,
dt,
p = 10^-6,
waterlevel = 10^-6,
na.replace = FALSE
)

Details
The function requires a set of input parameters, apart from the signal
vector. These parameters are contained in and read from the function
list_sensor()
and list_logger()
. Poles and zeros are used
to build the transfer function. The value s is the generator constant in
Vs/m. The value k is the normalisation factor. AD is the analogue-digital
conversion factor. If the signal was recorded with a gain value other than
1, the resulting signal needs to be corrected for this, as well.
Value
Numeric
vector or list of vectors, deconvolved signal.

Examples
## load example data set
data(rockfall)
## deconvolve signal with minimum effort
rockfall_decon <- signal_deconvolve(data = rockfall_eseis)
## plot time series
plot_signal(data = rockfall_decon,
main = "Rockfall, deconvolved signal",
ylab = "m/s")
## add new logger manually
logger_new <- list_logger()[[1]]
## add logger data
logger_new$ID <- "logger_new"
logger_new$name <- "logger_new"
logger_new$AD <- 2.4414e-07
## deconvolve signal with new logger
rockfall_decon <- signal_deconvolve(data = rockfall_eseis,
sensor = "TC120s",
logger = logger_new)
## Change the setup of a logger, here: Centaur AD is changed due to
## other than default Vpp value, according to AD = V / (2^24).
## extract default Centaur logger
Centaur_10V <- list_logger()[[2]]
## replace AD value
Centaur_10V$AD <- 20/(2^24)
