Bistabile Flip-Flop-Schaltungsanordnung

摘要

A bistable and stability controllable flip-flop circuit arrangement comprising two amplifiers each having an output and an input. Means define respective direct-current coupling paths for mutually coupling the respective output of each amplifier with the input of the other amplifier in such a manner that in each of both operating conditions one of both amplifiers assumes an active amplifying state and the other of both amplifiers is driven into an inactive non-amplifying state. There is also provided means defining a respective alternating current-feedback path incorporating phase-rotating impedances arranged between both amplifiers between their own respective input and output. A movable control body changes the value of at least one of the phase-rotating impedances such that selectively for the one or the other of both amplifiers a positive alternating current-feedback condition is fulfilled between its output and its input which renders unstable the amplifying state in which the relevant amplifier is functioning and via the direct current-coupling paths common to both amplifiers switches such amplifier into its other operating state.
