Abstract
An interference-suppression circuit produces an interference-reduced signal is indicated from output signals from a plurality of redundant functional blocks. A first extreme-value determination unit determines the specific output signal that represents a first extreme value from the output signals of the functional blocks. A processing unit offsets the output signals of the plurality of functional blocks against one another in such a manner that the interference-reduced signal is determined. The processing unit omits from consideration the first extreme value in determining the interference-reduced signal.

An interference-suppression circuit for producing an interference-reduced signal, the interference-suppression circuit comprising:
- a plurality of redundant functional blocks, each of which receive a same input signal and produce an output signal;
- a first extreme-value determination unit, which is configured to determine a specific output signal representing a first extreme value from the output signals of the plurality of functional blocks;
- a processing unit configured to offset the output signals of a majority of functional blocks against one another in order to determine the interference-reduced signal;
- wherein the processing unit is configured to omit the first extreme value from consideration when determining the interference-reduced signal.
A spacecraft, comprising:
- an interference-suppression circuit for producing an interference-reduced signal, the interference-suppression circuit comprising
- a plurality of redundant functional blocks, each of which receive a same input signal and produce an output signal;
- a first extreme-value determination unit, which is configured to determine a specific output signal representing a first extreme value from the output signals of the plurality of functional blocks;
- a processing unit configured to offset the output signals of a majority of functional blocks against one another in order to determine the interference-reduced signal;
- wherein the processing unit is configured to omit the first extreme value from consideration when determining the interference-reduced signal.
A method for producing an interference-reduced signal, the method comprising:
- producing, by a plurality of redundant functional blocks, an output signal based on receipt of a same input signal;
- determining, by a first extreme-value determination unit, a specific output signal representing a first extreme value from the output signals of the plurality of functional blocks;
- offsetting, by a processing unit the output signals of a majority of functional blocks against one another in order to determine the interference-reduced signal;
- wherein the processing unit omits the first extreme value from consideration when determining the interference-reduced signal.
