Graphical representation of oscillating signals, characterized by repeating patterns, visually depicts variations in amplitude over time. A common example is a sine wave, often utilized to represent alternating current (AC) voltage. Another manifestation is the square wave, composed of abrupt transitions between high and low states.
The creation of such a visual aid enables engineers, scientists, and technicians to analyze signal behavior, identify potential anomalies, and optimize system performance. Historically, the physical manipulation of drawing tools or analog equipment was employed; the introduction of digital oscilloscopes and software facilitates precision and complex signal rendering.
