Abstract:
A control apparatus for a gradient amplifier includes a differentiation unit. The differentiation unit forms a differentiation signal by differential processing from a current desired value signal of the gradient amplifier. At least one electrical low pass filter unit is connected in series with the differentiation unit, and/or at least one electrical high pass filter unit is connected in parallel with the differentiation unit.
