| Nowadays, FFT (Fast Fourier Transform) has become very popular because
of recent high-precision device technology. We give you some information
about FFT in this laboratory. |
|
| (1) Insight to FFT |
- See how the butterfly algorithm processes.
- Use complex vectors to explain it.
- Utilize symmetry and periodic angle of vectors.
|
| (2) FFT in VHDL |
- Design very fast FFT by using VHDL.
- Execute 1024-point FFT only in 10k cycles.
- See the process to convert C source to VHDL.
|
(3) dsPIC FFT  |
- A simple FFT analyzer.
- Works on dsPIC30F2012.
- See the spectrum of various music.
