摘要

P.C.M.变速器的发展经历了三种设备。第一种是:在七十年代初，使用晶体管(t.t.l);第二种是:1975年前后，终端设备采用7种专用大规模集成电路，中继器继续使用目录元器件;可以合理地认为，第三类设备，在八十年代将配备特殊的大规模集成电路，这将在后面描述。

Integrated circuits of P.C.M. transmissions

The development of P.C.M. transmissions went through three sorts of equipments. The first kind was: in the early seventies, the use of transistors (T.T.L.); the second kind was: towards 1975, 7 specialized LSI were used in the terminal equipments, while the repeaters went on using the catalogue components; it can reasonably be thought that the third kind of equipments, in the eighties will be equiped with special LSI circuits which will be described later.
