Abstract

Certain switching network components require a first transmitter for the derivation of a base current (ib) from a collector current (ic) and a second transmitter for the transmission of a pulse (S). The problem to be solved is to reduce the energy consumption of these two transmitters. The latter consist of a single transmitter (Ü) with three coils (1, 2, 3) which serves both as a current transmitter for the base current (ib) and as an information transmitter for the pulse (S). Application in particular in monitors, television receivers, and video recorders.
