Basic Principles/Science of Media Technology
- "Broadcasting, cable, and new media make use of facsimile technology, reproducing sound and sight in other forms. The better the correspondence between the facsimile and the original, the higher the fidelity."
- Transduction is the process of "changing energy from one form to another; it is at the heart of audio and video technology. Transduction can be analog—the transformed energy resembles the original—or digital—the original is transformed into a series of numbers." Examples of transduction include energy going from physical energy to electrical, from light to electrical and from electrical to electromagnetic (radio waves).
