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:
“I perceived that to express those impressions, to write that essential book, which is the only true one, a great writer does not, in the current meaning of the word, invent it, but, since it exists already in each one of us, interprets it. The duty and the task of a writer are those of an interpreter.”
—Marcel Proust (1871–1922)
“The only people who treasure systems are those whom the whole truth evades, who want to catch it by the tail. A system is just like truth’s tail, but the truth is like a lizard. It will leave the tail in your hand and escape; it knows that it will soon grow another tail.”
—Ivan Sergeevich Turgenev (1818–1883)
