Overview

Signal Processing Resource Center » LabVIEW Signal Processing Shipping Examples » Fast Fourier Transform of a Pulse (2-D)

This example demonstrates how to use the FFT VIs to compute the two-dimensional FFT, using a simple rectangular step function within a square image as the original 2D image to transform. The "array size" control sets both dimension sizes of the 2D square image. The "delay x" control sets the lower-left x coordinate of the rectangle step function. The "width x" control sets the x-dimension size of the rectangle step function. The "delay y" control sets the lower-left y coordinate of the rectangle step function. The "width y" control sets the y-dimension size of the rectangle step function.

show block diagram also
For those of us not at a computer with LabVIEW, it would be helpful to show the block diagram as well as the front panel.
