- Description:
-
- The FFT programs perform a frequency analysis using the fast Fourier
- Transform. They expect an Armadeus formatted input file and output
- graphs in Draw format. FFT_2D outputs a two dimensional graph with
- level as y-axis and frequency as x-axis. FFT_3D option 3D outputs a
- three dimensional graph with frequency along the y-axis, time along
- the x-axis and level is deflection. FFT_3D option sonograph outputs
- a three dimensional graph with frequency along the y-axis, time along
- the x-axis and level is black level. C sources and an example input
- file are included.
-
- An ARM3 or later is required due to use of the SWP instruction.
- A Floating Point Accelerator (FPA) is not required but would be useful.
- The Desktop Development Environment (DDE) is required for the desktop
- interface but the programs can be run from the command line without it.
