MediaTech: Audio/Video Tech (Basics) (U4-P1) fa12

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."
At what point or points in signal processing does transduction occur for traditional (over-the-air) radio?
