ondograph
ondograph (ˈɒndəʊˌɡrɑːf; -ˌɡræf) n (General Physics) an instrument for producing a graphical recording of an alternating current by measuring the charge imparted to a capacitor at different points in the cycle[C20: from French, from onde wave + -graph]ondographan instrument for recording oscillatory variations, as those in alternating currents. — ondogram, n.See also: Instrumentsondograph
ondograph[′än·də‚graf] (electronics) An instrument that draws the waveform of an alternating-current voltage step by step; a capacitor is charged momentarily to the amplitude of a point on the voltage wave, then discharged into a recording galvanometer, with the action being repeated a little further along on the waveform at intervals of about 0.01 second. |
