Current Systems

A modern system, having gained ground since the early 1990s, uses a personal computer and special software in place of much of the custom equipment. The sound card of a PC, with special processing software, acts as a modem. The computer screen provides the output. A small digital camera or digital photos provide the input.

Famous quotes containing the words current and/or systems:

    We all participate in weaving the social fabric; we should therefore all participate in patching the fabric when it develops holes—mismatches between old expectations and current realities.
    Anne C. Weisberg (20th century)

    I am beginning to suspect all elaborate and special systems of education. They seem to me to be built up on the supposition that every child is a kind of idiot who must be taught to think.
    Anne Sullivan (1866–1936)
