Abstract

A device for processing data adapted for being converted between an analog format and a digital format, the device having a scrambling unit adapted for scrambling the data based on at least a part of the data to thereby decorrelate the data in the analog format with respect to the data in the digital format.

Claims (45)

1. A device for processing data, the device comprising:

a scrambling unit adapted for scrambling a digital version of the data into scrambled digital data based on at least a part of the digital version of the data which is used as a signal to scramble the data, to thereby decorrelate the scrambled digital data with respect to an analog version of the data,

wherein said scrambling comprises logically combining bits of the digital version of the data with each other, and

wherein the at least a part of the digital version of the data which is used as a signal to scramble the data is obtainable from the scrambled digital data, but is not appended to the scrambled digital data.

2. The device of claim 1 , wherein the scrambling unit is adapted for scrambling currently processed data based on the currently processed data.

3. The device of claim 1 , wherein the scrambling unit is adapted for scrambling currently processed data based on previously processed data.

4. The device of claim 1 , wherein the scrambling unit is adapted for scrambling currently processed data based on the currently processed data and based on previously processed data.

5. The device of claim 1 , wherein the scrambling unit is adapted for scrambling the data based on exactly one bit of the data.

6. The device of claim 1 , wherein the scrambling unit is adapted for scrambling the data based on the entire data.

7. The device of claim 1 , wherein the scrambling unit is adapted for scrambling the data by logically combining the data with at least a part of the data.

8. The device of claim 1 , wherein the scrambling unit is adapted for scrambling the data by logically combining the data with at least a part of the data using an invertible Boolean function.

9. The device of claim 8 , wherein the invertible Boolean function is one of the group consisting of an XOR function, an AND function, an OR function, an inverter function, and any logical combination of an XOR function, an AND function, an OR function, and an inverter function.

10. The device of claim 1 , wherein the scrambling unit is adapted for scrambling the data based on at least a part of the data and based on a random signal provided by a random signal generation unit.

11. The device of claim 1 , further comprising a conversion unit for converting the data into converted data.

12. The device of claim 11 , wherein the conversion unit is adapted for converting between analog data and digital data.

13. The device of claim 11 , wherein the conversion unit is adapted for converting digital data as the data into analog data as the converted data.

14. The device of claim 11 , wherein the conversion unit is adapted for converting analog data as the data into digital data as the converted data.

15. The device of claim 1 , further comprising a descrambling unit adapted for descrambling the scrambled data based on at least a part of the data.

16. A device for processing data, the device comprising:

a scrambling unit adapted for scrambling a digital version of the data into scrambled digital data based on at least a part of the digital version of the data, to thereby decorrelate the scrambled digital data with respect to an analog version of the data,

wherein said scrambling comprises logically combining bits of the digital version of the data with each other, and

wherein the scrambling unit is adapted for scrambling the data based on a Least Significant Bit of the data.

17. A measurement apparatus, comprising:

a data generation unit adapted to generate data related to a measurement carried out by the measurement apparatus; and

a device, the device comprising

a scrambling unit adapted for scrambling a digital version of the data into scrambled digital data based on at least a part of the digital version of the data which is used as a signal to scramble the data, to thereby decorrelate the scrambled digital data with respect to an analog version of the data,

wherein said scrambling comprises logically combining bits of the digital version of the data with each other, for processing the generated data so as to scramble the generated data based on at least a part of the generated data, and

wherein the at least a part of the digital version of the data which is used as a signal to scramble the data is obtainable from the scrambled digital data, but is not appended to the scrambled digital data.

18. The measurement apparatus of claim 17 , further comprising at least one of an analog-to-digital converter, a digital-to-analog converter, a sensor device, a test device for testing a device under test or a substance, a device for chemical, abiological and/or pharmaceutical analyzer, a fluid separation system adapted for separating compounds of a fluid, a capillary electrophoresis device, a liquid chromatography device, a gas chromatography device, an electronic measurement device, and a mass spectroscopy device.

19. A method of processing data, the method comprising:

scrambling a digital version of the data into scrambled digital data based on at least a part of the digital version of the data which is used as a signal to scramble the data, to thereby decorrelate the scrambled digital data with respect to an analog version of the data,

wherein said scrambling comprises logically combining bits of the digital version of the data with each other, and

wherein the at least a part of the digital version of the data which is used as a signal to scramble the data is obtainable from the scrambled digital data, but is not appended to the scrambled digital data.

20. A non-transitory computer-readable storage medium, in which a computer program of processing data is stored, which computer program, when being executed by a processor, is adapted to control or carry out a method of:

scrambling a digital version of the data into scrambled digital data based on at least a part of the digital version of the data which is used as a signal to scramble the data, to thereby decorrelate the scrambled digital data with respect to an analog version of the data,

wherein said scrambling comprises logically combining bits of the digital version of the data with each other, and

wherein the at least a part of the digital version of the data which is used as a signal to scramble the data is obtainable from the scrambled digital data, but is not appended to the scrambled digital data.

21. A device for processing data, the device comprising:

a descrambling unit adapted for descrambling scrambled digital data into a digital version of the data based on at least a part of the scrambled digital data which is used as a signal to scramble the data so that the scrambled digital data provided at a digital input of the descrambling unit is decorrelated with respect to an analog version of the data,

wherein said descrambling comprises logically combining bits of the scrambled digital data with each other, and

wherein the at least a part of the digital version of the data which is used as a signal to scramble the data is obtainable from the scrambled digital data, but is not appended to the scrambled digital data.

22. A method of processing data, the method comprising:

descrambling scrambled digital data into a digital version of the data based on at least a part of the scrambled digital data which is used as a signal to scramble the data so that the scrambled digital data provided at a digital input is decorrelated with respect to an analog version of the data,

wherein said descrambling comprises logically combining bits of the scrambled digital data with each other, and

wherein the at least a part of the digital version of the data which is used as a signal to scramble the data is obtainable from the scrambled digital data, but is not appended to the scrambled digital data.
