TD_​IDFFT

This function simply reverses the effects of the forward transform. It takes as its input either a logical-runtime series containing complex number elements, or, alternatively, a logical-runtime series containing amplitude-phase pair elements; runs them through a reverse-transform summation formula; and outputs the original signal (time series or spatial series or arbitrary discrete series) that was input into the TD_DFFT to generate the Fourier coefficients.

Options

HUMAN_READABLE

Required Parameter when input rows are in raw format. Informs the TD_IDDFT as to whether the incoming DFFT coefficient rows are in a human-readable / plottable form; or if they are output in the raw-form, which is equivalent to how the 'R' and 'PYTHON' programs produce DFFT results. A value of '1' means true, output in human readable form; a value of '0' means false, output in raw form. Default is true - input rows are in Human Readable format.

Volatile

Specifies whether the table should be a VOLATILE table. If true, then the table is automatically deleted, otherwise it is users responsibility to remove or clean it up for space.
