DELPHI写的FFT程序

This a very simple program to fft remove noise from a signal}
The fft algorithm is found in Jan Teuber's book Digital Image Processing.

The signal is composed by two sines with varying frequencies and
amplitudes, added some random noise with even lower frequencies

By dragging the scrollbar you can remove either of these}
components.

I've been looking myself for a simple example for a while written in
Pascal, so i hope this can help somebody.

Feel free to modify the program.
