D-AMPS is a North American 2G digital cellular radio standard that essentially is a digital version of the earlier analogy AMPS specification. D-AMPS operates in the same 800 MHz band as AMPS and the two can coexist in the same network. D-AMPS uses the same 30 kHz bands as AMPS, and supports up to 416 frequency channels per carrier. D-AMPS employs time division duplex (TDD) to subdivide each frequency channel into six time slots, each of which operates at 8 kbps. Each call initially uses two time slots in each direction, for a total of 16 kbps.

Digital audio uses digital signals for sound reproduction. This includes analogy-to-digital conversion, digital-to-analogy conversion, storage, and transmission.

A generic term for any type of cable television distribution using digital video compression or distribution. The technology was originally developed by Motorola.

Using MPEG encoding, digital cable is an enhanced service from the cable companies that provides an option to the regular analogy TV. Advantages are on-screen program guides, a sharper picture and more channels of paid and on-demand programs. Unlike "digital satellite TV," which requires a dish on the roof, digital cable, also known as "digital terrestrial TV (DTTV)," is delivered over the same coaxial cable wired into the home or office.

A digital camera (also digicam or camera for short) is a camera that takes video or still photographs, or both, digitally by recording images via an electronic image sensor.
