A method for producing an output data stream includes picking up and digitalizing a combustion chamber signal to a combustion chamber signal data stream and, simultaneously therewith, picking up and digitalizing a crankshaft angle signal to a crankshaft signal data stream. The combustion chamber signal data stream is split or duplicated into a first and a second combustion chamber signal data flow. The first combustion chamber signal data flow is filtered to a first filtered combustion chamber signal data stream and then transformed to a first transformed combustion chamber signal data stream. The second combustion chamber signal data flow is transformed to a second transformed combustion chamber signal data stream. The first and second transformed combustion chamber signal data streams are combined to an output data stream which comprises the first and second transformed combustion chamber signal data streams in a respective first and second crankshaft angle range.

Method for producing a combustion space signal data stream with interference suppression

To reduce the complexity of an indicating systemon an internal combustion engine for determining a parameter, the invention provides that on the basis of the measured variable a computing unitfor the indicating systemcomputes crank angle information, and on the basis of the crank angle information thus computed and the measured variable determines an engine parameter.
