oscillator
의미: A device or circuit that produces a repetitive, alternating signal — typically a sine wave or square wave at a specific frequency.
Oscillators are fundamental to electronics, providing the clock signals that synchronise digital circuits, generating radio frequencies for communication, and producing tones in musical instruments and alarm systems. A crystal oscillator uses the vibration of a quartz crystal to maintain extremely precise timing — the basis of all modern clocks and watches. The related verb 'oscillate' means to move back and forth at a regular speed, and is also used figuratively to mean wavering between opinions.

기원과 역사
From Latin oscillare (to swing), from oscillum (a small face or mask hung as a decoration that would swing in the wind). The suffix '-ator' denotes an agent or device. The electronic sense developed in the early 20th century.
