Abstract

The system includes a microprocessor (SK), to which is applied a digital input signal (S via a resistive voltage divider (R1,R2). A voltage detector (UD) is provided which controls, as function of amplitude the operating voltage (UB) by means of switches (AT,TR) which switch in another resistance (R3) in parallel to resistance (R2) of the voltage divider (R1,R2). The switch (AT) is contained within the microprocessor (SK) and the switch (TR) is an external transistor.
