Abstract
A circuit arrangement for generating representations of supply voltages that includes a first path that receives control signals, the first path having a subtracter for forming a difference signal from two of the control signals and a low pass filter to receive the difference signal. A second path receives the control signals, the second path includes a second low pass filters that passes frequencies higher than the first low pass filter does. Output signals of the first and second paths are fed to a combination network which, as a function of the difference between the output signals of the first and second paths, passes on the output signals of one of the first and second paths.
