FFT Laboratory
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.
