By means of the same, it is practicable to rotate a body of considerable weight with uniform and adjustable velocity, and it lends itself to the operation of circuit controllers, curve tracers, and all kinds of such devices. It will be found most useful in tracing current or electromotive force curves and a variety of diagrams. . . ."
It would be interesting, from an historical point of view, to figure out how Tesla might have used the tikker for, "tracing current or electromotive force curves and a variety of diagrams. . . ."
Original poster: "Gav D" <gdingley@xxxxxxxxx> Hi Ed, Gary et al, didn't Tesla experiment with stroboscopic observation of waves, or at least frequency? If so could he not have detected frequency components as well as the main carrier using this method (using a beat frequency method of some sort). Not as good as an oscilloscope or spectrum analyser, but perhaps he would have been able to to pick-out components with this method? Gavin
