Digital Technology & Electronic Transmissions
Prior to digital technology, electronic transmission was limited to analog technology, which conveys data as electronic signals of varying frequency or amplitude that are added to carrier waves of a given frequency. Broadcast and telephone transmissions have conventionally used analog technology. Digital technology is primarily used with new physical communications media, such as satellite and fiber optic transmission. It can provide speeds of roughly 128,000 bits-per-second over regular telephone lines. In practice, most people will be limited to 56,000 or 64,000 bits-per-second. The links included herein relate to digital delivery.
