empymod.transform.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.
