Abstract

A method of providing a display signal, wherein digital data to be displayed has associated with it statistical values determined for pre-determined sized blocks of the digital data, comprising the steps of: determining display scaling parameters; determining from the display scaling parameters the extent to which the statistical values are suitable to use in place of some or all of the digital data when determining which data points of either the digital data and/or statistical values to display; determining the data points to display; reading the digital data and/or statistical values to be displayed; and generating the display signal from the digital data and/or statistical values.

Claims

1. A method of providing a display signal, wherein digital data to be displayed has associated with it statistical values determined for pre-determined sized blocks of the digital data, comprising the:

determining display scaling parameters;

determining from the display scaling parameters the extent to which the statistical values are suitable to use in place of some or all of the digital data when determining which data points of either the digital data and/or statistical values to display;

determining the data points to display;

reading the digital data and/or statistical values to be displayed; and

generating the display signal from the digital data and/or statistical values.

2. The method according to claim 1, wherein statistical values include some or all of the minimum value or maximum value of the digital data.

3. The method according to claim 2, wherein the data points to display include both the minimum and maximum value of the digital data.

4. The method according to claim 2, wherein statistical values include some or all of the standard deviation, some of values, or some of squares of values.

5. The method according to claim 1, wherein the digital data to be displayed is obtained by sampling an analog signal and converting the samples to digital data.

6. The method according to claim 1, wherein the process substantially occurs in real time.

23. The method of claim 1 further comprising storing the digital data and/or statistical values.

7. A system for providing a display signal, wherein digital data to be displayed has associated with it statistical values determined for predetermined sized blocks of the digital data, comprising:

display scaling parameter determination means;

processing means for determining, from the display scaling parameters, the extend to which the statistical values are suitable to use in place of some or all of the digital data when determining which data points of either the digital data and/or statistical values to display;

processing means for determining which data points to display;

data reading means for reading the digital data and/or statistical values to be displayed; and

display means for generating the display signal from the digital data and/or statistical values.

8. The system according to claim 7, wherein statistical values include some or all of the minimum value or maximum value of the digital data.

9. The system according to claim 8, wherein the data points to display include both the minimum and maximum value of the digital data.

10. The system according to claim 8, wherein statistical values include some or all of the standard deviation, some of values, or some of squares of values.

11. The system according to claim 7, wherein the digital data to be displayed is obtained by sampling an analog signal and converting the samples to digital data.

12. The system according to claim 7, wherein the process substantially occurs in real time.

24. The system according to claim 7 further comprising a string means for storing the digital data and/or statistical values.

13. A computer program product for providing a display signal, the computer program product comprising a computer readable medium having computer readable code thereon, including program code comprising:

instructions and data for causing a processor to perform determination of display scaling parameters;

determination, from the display scaling parameters, the extent to which the statistical values are suitable to use in place of some or all of the digital data when determining which data points of either the digital data and/or statistical values to display;

determination of the data points to display;

reading of the digital data and/or statistical values to be displayed; and

generation of the displayed signal from the digital data and/or statistical values.

14. The computer program product for providing a display signal according to claim 13, wherein statistical values include some or all of the minimum value or maximum value of the digital data.

15. The computer program product for providing a display signal according to claim 14, wherein the data points to display include both the minimum and maximum value of the digital data.

16. The computer program product for providing a display signal according to claims 14, wherein statistical values include some or all of the standard deviation, some of values, or some of squares of values.

17. The computer program product for providing a display signal according to claims 13, wherein the digital data to be displayed is obtained by sampling an analog signal and converting the samples to digital data.

18. The computer program product for providing a display signal according to claims 13, wherein the process substantially occurs in real time.
