rectangular
含义: Having the shape of a rectangle, with four right angles and opposite sides of equal length, or in signal processing, describing a waveform that alternates abruptly between two fixed levels.
In everyday use, 'rectangular' simply describes shape, but in engineering and mathematics it carries additional precision. A rectangular (or square) wave is a digital signal that switches between high and low states, fundamental to computing and digital communications. In mathematics, rectangular coordinates refer to the Cartesian system. The term is universally understood but gains technical specificity depending on context.
