Control logic for adaptation to the amplitude of a noise signal

摘要

The invention relates to the field of processing-related acquisition of signals by an automatic adjustment of the dead zone of a nonlinear transmission element. The signals, when deviating from the set value, pass via a threshold switch with adjustable dead zone to the memory intended for this purpose. These memories are followed by a control logic. It logically combines the memory outputs with their reset inputs. This takes into consideration other updated boundary conditions. The influences due to the change in frequency can thus be eliminated. Automatic adjustment of the threshold value is made possible as a function of the change in the noise value amplitude.
