Abstract:
An input circuit for processing an analog input signal in the form of an analog measurement signal with a modulated additional signal and for converting the input signal into a serial bit stream having a frequency distribution of high levels which is proportional to the input signal, and a method for operating such an input circuit, the input circuit including a device for comparing an instantaneous voltage value of the input signal with a variable comparison value and a device for adapting the comparison value to an instantaneous value of the generated bit stream, is provided.
