This projects implements an eight point Decimation In Time Fast Fourier Transform.

The internal data buses width and representation will be discussed and explained FFT design consideration .

Twiddle factors representation is also described. For instance for the third stage FFT calculation, fractional numbers are required such as .070710678.see FFT Twiddle Factors

The FFT also introduce some gain, which proportional to the number of points. This is discussed at FFT gain compensation ....
