METHOD AND CIRCUIT FOR REGULATING THE SIGNAL LEVEL FED TO AN ANALOG-DIGITAL CONVERTER

摘要

The invention relates to a method and circuit for regulating the signal level fed to an analog-digital converter. In order to regulate the signal level fed to an analog-digital converter, the rate of change at which the output signal of the analog-digital converter (4) is temporally modified, especially the modification rate of an output bit of the analog-digital converter, is measured and compared with the specified value (SP). The signal level fed to the analog-digital converter (4) is adjusted according to the result of this comparison.
