Switch over system connecting analogue components to central control - has very long analogue bus line and bus amplifier to control output impedance connected between bus line and central control

摘要

The switch-over system for connecting analogue components (13) to a central control (3). The central control has a logic processor (7) to control a switch-over process and a very long analogue bus line (5'). The bus line is connected to the central control via at least one amplifier (14) to control (15) the output impedance connected to the central control. Each system component to be switched is associated with a switch (10). The switch is controlled such that it connects the components to the analogue bus line under control of the processor and via a logic bus line (6'). USE/ADVANTAGE - Especially suitable for connecting radio telephones with microphones. Simple, compact and flexible system. Bus amplifier can be so driven that it exhibits low or high output impedances with reduced difficulties.
