FFTKNL

Perform a 16-bit discrete Fourier transform.

Example

Description

20 OUTPUT 723;"FFTKNL TRA,TRB;"

The FFTKNL performs a discrete Fourier transform on the speci￿ed traces, overlaying them with the results. Both traces must be the same length and the length must be a power of two. The two traces represent the real and imaginary components of one complex-value trace. FFTKNL does no other normalizing, scaling, clipping, or magnitude determination.
