oscillogram

noun

1. A record produced by an oscillograph or oscilloscope.

   “The R.M.S. value of the pressure was taken from the oscillogram by taking the square root of the average value of the squares of a number of equi-distant ordinates; the R.M.S. value of the current was obtained in the same way from the current oscillogram, and the two values multiplied together always gave a value agreeing to within 1 per cent. of that obtained by first multiplying the ordinates taken from the current and voltage oscillograms and then taking the mean.”

   “The process was controlled through oscillograms that showed the moments of breakage of the graphite rods.”

   “From these oscillograms, it is visible that the resonator oscillations are noticeably inharmonic and asymmetric ones.”
