We present the test results for an NMOS transimpedance preamplifier with 50 Ohm drive capability and built in AGC function.

Telegraph signalling waveforms consist of a series of mark-space or space-mark transitions that represent points at which the rate of change of information is a maximum.

Basic principles are described of a 960-channel carrier system developed jointly by the Standard Telephone and Cables Ltd., Standard Elektric Lorenz.

Constructional version is described which follows the British Post Office 62-type design.

Constructional version based on single-sided 225 mm deep racks is described.

Transistors, because of their reliability, small power consumption, unci small si/x; find a natural field of application in electronic computers and data transmission systems.

Solid-state long-haul analog communication systems are being designed for higher frequencies to meet the growth in demand.

Telecommunication systems used in France have their CPU powered by DC/DC converters. However, the peripherals have to be powered by AC current.

A large proportion of the telephone calls made require connections to be set lip in more than one central office.

A pulse regenerative amplifier is a bistate circuit which introduces gain and pulse reshaping in a pulse transmission or digital data processing system.
