The crossbar tandem switching system, originally designed for switching between local dial offices, will now play an important role in nationwide dialing.
THE RAPID mechanization of the local telephone plant throughout the Bell System, together with the continuous expansion of subscriber dialing areas, has made necessary the development of an automat
New low-lying excitations are observed by inelastic light scattering at filling factors nu = p/(phi*p+-1) of the fractional quantum Hall regime with phi = 4.
New low-lying excitations are observed by inelastic light scattering at filling factors nu = p/(phip+=1) of the fractional quantum Hall regime with phi = 4, Coexisting with these modes throughout
In a quantum dot with three leads, the transmission matrix t(12) between two of these leads is a truncation of a unitary scattering matrix S, which we treat as random.
Crossover networks are introduced as a new type of interconnection network for applications in optical computing, optical switching, and signal processing.
Large scale production of reed type contacts has proved them to be economic and technically suitable substitutes for conventional mechanical types used in telecommunications switching networks.
We show that the tolerance to in-band crosstalk due to a slight misalignment of the filtering function can be relaxed.
ROSSTALK and noise are important factors in cable carrier transmission as outlined in the paper "A Carrier Telephone System for Toll Cables" by Messrs. C. W. Green and E. I. Green.
