Sure, it’s wide for the tadpole that’s trying to swim across it, but it wouldn’t be wide for an elephant. There is, of course, no answer to this question. Let’s say we’re taking a stroll in the woods and I point to a stream. This brief analysis has already uncovered a problem.
The term in question is obviously composed of “band” and “width.” This “band” refers to a band, or range, of frequencies, and “width” refers to the appearance of this band when viewed in the frequency domain.Ī frequency-domain representation of a signal composed of two single-frequency sine waves. Whenever possible, I like to start with a definition that is based on a term’s constituent words, or on the etymology when constituent words are not readily recognizable. The Definition of Bandwidth: The Width of the Band Another source of confusion, or at least uncertainty, is found among subtle details that we can sometimes ignore. I sincerely wonder how many of us could immediately produce a coherent definition or explanation of the word “bandwidth.” Much of the difficulty originates from the fact that the word has several meanings. Analog circuits, test and measurement, RF systems, digital communications, computing-the concept of bandwidth is integral to modern electronic technology. The term “bandwidth” arises in a wide variety of engineering discussions. This article explores the surprisingly complicated details associated with a word that we frequently use but perhaps don’t fully understand.
