oscilloscope [oss-sill-oh-scope]
Noun
an instrument that produces a visual representation of an oscillating electric current on the screen of a cathode-ray tube
| oscilloscope (-sl-skp) An electronic instrument used to observe and measure changing electrical signals. The amplitude of the signal as it varies with time is displayed graphically on a screen as a line stretching from left to right, with displacements up and down indicating the amplitude of the signal. Oscilloscopes are used to diagnose problems in electronic signal-processing devises, such as computers or stereos, and to monitor electrical activity in the body, such as that of heartbeats. |
