Analog Fouriertransformation: 17 Nov 2014, Pre-digital computer 'cranks out' Fourier Transforms. Boffins get a handle on pre-digital computer, restore it to working order:
Citat: "...designer Albert Michelson...As “Engineer guy” Bill Hammack explains in the video below (third in his series), the machine operation is surprisingly simple: the user sets the wave they want analysed in the rocker bars of the machine and turns the crank. The pen outputs the coefficients - in other words, the sine waves (fundamental and harmonic) that make up the input function, and their relative amplitude...That limits it to analysing a waveform with 20 samples. However, as they note in the book, Michelson also constructed an 80-sample machine..."
