fourier_dlf
(fEM, time, freq, ftarg)[source]¶ Fourier Transform using the Digital Linear Filter method.
It follows the Filter methodology [Ande75], using Cosine- and Sine-filters; see
hankel_dlf()
for more information.The function is called from one of the modelling routines in
empymod.model
. Consult these modelling routines for a description of the input and output parameters.This function is based on get_CSEM1D_TD_FHT.m from the source code distributed with [Key12].
- Returns
- tEMarray
Returns time-domain EM response of fEM for given time.
- convbool
Only relevant for QWE/QUAD.
