Multiple utilisation circuit for alphanumeric opto-electronic display - supplies digital and/or analog signal to data converter, concerning HF receiver or amplifier combination

摘要

The display has a number of symbol positions and is incorporated in a h.f. receiver. All digital and/or analog signals, provided for alternate optical display, are supplied to a data converter. These signals are related to the tuning or operating condition of the receiver, or to a combination of a h.f. receiver with a l.f. amplifier. The individual signal outputs of the data converter are coupled to the following inputs of an electronic data selector switch. The output side roots of this switch are linked to the signal inputs of a driver circuit, coupled in front of the opto-electronic display. An automatic and/or triggerable clock pulse generator is provided for cyclic and/or defined positioning of the data selector switch. Pref. the latter operates cyclically, while any desired dwelling periods in the individual positions are preprogrammed by the clock Pulse generator.
