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.
The deviation from perfect linearity in a repeater amplifier for a high-capacity, long-haul system is very small by normal standards.
Long distance communication using digital transmission is not new but was used by man in his earliest communication system.
Recent articles in the literature have treated the theory and properties of semiconductor devices. In particular, papers by Messrs.
It is proposed to discuss some of the properties of transistors which are applicable to switching or pulse-type circuits, to develop elementary analysis methods and to describe a few circuits.
A mathematical treatment is given of the problem of transit time and space charge effects in a plane diode, formulae being derived applicable to the beginning of an electronic discharge, as well as
In a recent paper 1 , J. R.
We have observed in a low density two-dimensional hole system (2DHS) of extremely high quality (with hole density p=1.6x10(10) cm(-2) and mobility mu=0.8x10(6) cm(2)/V s) that, as the 2DHS is conti
At low Landau level filling of a two-dimensional electron system, typically associated with the formation of an electron crystal, we observe local minima in R-xx at filling factors nu = 2/11 , 3/17
