| oscilloscope (ə-sĭl'ə-skōp') Pronunciation Key
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. |
