Attenuation-free electronic switch

摘要

Electronic switch for use as a crosspoint in switching networks of space-division telephone exchanges where it is connected to function as an open circuit stable negative resistance provding ON-attenuation compensated signal transmission, the switch being constituted by a circuit arrangement which lends itself to monolithic integration and which, when switched off, prevents undersirable attenuation of crosspoints connected to the same row or column of the switching system.
