- ART_SPEC
- An ART that was produced by the TD_DFFT function. The ART_SPEC is required to contain the ART_SPEC parameters TABLE_NAME, and PAYLOAD with FIELDS and CONTENT. Do not use any other ART_SPEC parameters.
- SERIES_SPEC
- A series containing Fourier coefficients that is passed in to the TD_DFFTCONV.
- FUNC_PARAMS
-
Name Data Type Description CONV String The type of conversion to be performed by the TD_DFFTCONV function. Options are: - HR_TO_RAW: Convert from human readable to raw form.
- RAW_TO_HR: Convert from raw form to human readable form.
HERTZ_SAMPLE_RATE FLOAT [Optional] The sample rate as a floating point constant, in hertz. Only valid with FREQ_STYLE(K_HERTZ). A value of 10000.0 indicates that the sample points were obtained by sampling at a rate of 10,000 hertz. FREQ_STYLE String [Optional] The format or values associated with the x-axis of the output.
Choices are:- K_INTEGRAL: Integer representation.
- K_SAMPLE_RATE: Integer normalized to number entries, with ranges from -0.5 to +0.5.
- K_RADIANS: Radian ranges from -π to +π.
- K_HERTZ: Frequency in hertz. Must be used in conjunction with HERTZ_SAMPLE_RATE.
The default is K_INTEGRAL.
- INPUT_FMT
- No INPUT_FMT options are available for this function.
- OUTPUT_FMT
A complex number that can be in rectangular (real, imaginary) or polar (amplitude, phase) form. The output options for univariate series are the following:
- COMPLEX
- AMPL_PHASE_DEGREES
- AMPL_PHASE_RADIANS
The default is COMPLEX.
