Radio control appts. for models - has demountable function control board coupled to analogue switches and time division multiplexers

摘要

A radio control operator sets various control potentiometers and switches which are arranged on a programmable intermediate circuit on a plug-in plate. At least two output connectors are connected to the circuit and an analogue switch. Each switch is coupled cyclically in time division multiplex mode to a common summation point (Po) by way of an inverter. The circuit is intended for radio control, especially of models, by an amplitude or frequency modulated carrier wave in which the settings of potentiometers or switches for predetermined control functions are cyclically modulated on the carrier.
