Harmonic Analyzer Mechanical Fourier Computer Par HackadayLe [2014-11-18] à 10:04:57
Présentation : If you re into mechanical devices or Fourier series or both , you ve got some serious YouTubing to do. The Engineer Guy has posted up a series of four videos Introduction, Synthesis, Analysis, and Operation that demonstrate the operation and theory behind a 100-year-old machine that does Fourier analysis and synthesis with gears, cams, rocker-arms, and springs. In Synthesis, The Engineer Guy explains how the machine creates an arbitrary waveform from its twenty Fourier components. In retrospect, if you re up on your Fourier synthesis, it s pretty obvious. Gears turn at precise ratios to each other to Read more
