DeconTrace: Deconvolve Instrument Response (Single Trace)

Description

Deconvolves a discrete instrument response from a seismic trace.

Usage

DeconTrace(x, DPZ, fl = 0.05, fh = NaN, bitweight = NULL, dec = 1)

Arguments

x

Trace from which instrument response is deconvolved

DPZ

Discrete instrument response list (from MakeDPZ, for example)

fl

Low corner of filter (NaN for no high-pass filtering) (Hz)

fh

High corner of filter (NaN for no low-pass filtering) (Hz)

bitweight

Optional counts-to-volts factor for data in counts (volts/counts)--NULL if data are already in volts

dec

Oversampling/decimation factor (optional)

Value

Deconvolved velocity trace (vector).

Details

Discrete instrument responses are specific to a given sampling rate. If the response you give has a different sample rate (given by DPZ$dt) from the trace x, you will get incorrect results. DPZ$dt * dec should be equal to the trace's sample interval.
