How to plot cross-corr​elation in terms of the real time?

Usually the cross-correlation or the auto-correlation results are plotted vs. the lag(tao). But how can I plot it vs. the real time of the input signal? I have two same length input signals having same input time.

I am using LabView 7Express. What I use is the "convolution and correlation" VI, without the 'Express' however ... I mean, if both my input signals are L-length, the result of the correlation will be 2L-length, i.e. the length is doubled. But I want to keep the original signal size, making the result L-length as well, and have the same time origin as the input signals. I mean, if my input signals are from 0-1 second, I also expect to see the cross-correlaton is within 0-1 second, having the same data points. Thanks a lot!

    Adobe Bridge, lightroom and your file browser (windows explorer or Mac Finder) can select multiple pictures at once and then delete. If you are looking for more than that for information, you will need to be more specific at what your doing, what OS you have, and version of software your using. If necessary post screen shots so we can see what your doing. The more information we have the more detailed of an explaination can can give back to you.

    Safari only lets me to sign in to one hotmail account at any one time. If I am signed in to one account and I open a new window (or tab) the existing hotmail account I am signed in to opens again (I want to sign into second account simultaneously). So I am trying to sign in to 2 hotmail accounts at the same time. Does that makes sense?

    I am facing some problems while checking Build date of my Application file( .dll)
    I have tried to use GetFileDate API. But it is not supporting for realtime Target..
    So i have tried __DATE__ macro.. That also having some problems..
    How to get last Build date of a dll from the real time target  ??
    Please Help to solve this....

  • BAdI........How are they used in the real time scenario.

    Im a rookie in ABAP development and i was wondering that how we use the BAdI enhancement technique in the real time scenarios. Like do we get create them or we have few already built BAdI's which we work on? Can any body please explain how this works.

    Hi Ramana,
    Business add-ins are enhancements to the standard version of the system.
    Business Add-In is a new SAP enhancement technique based on ABAP Objects.
    They can be inserted into the SAP system based on specific user requirements.
    Each Business Add-In has:
    • at least one Business Add-In definition
    • a Business Add-In interface
    • a Business Add-In class that implements the interface
    In order to enhance a program, a Business Add-In must first be defined
    Subsequently two classes are automatically generated:
    • An interface with ‘IF_EX_’ inserted between the first and second characters of the BADI name.
    • An adapter class with ‘CL_EX_’ inserted between the first and second characters of the BADI name.
    The Application developer creates an interface for this Add-In.
    There are multiple ways of searching for BADI.
    • Finding BADI Using CL_EXITHANDLER=>GET_INSTANCE
    • Finding BADI Using SQL Trace (TCODE-ST05).
    • Finding BADI Using Repository Information System (TCODE- SE84).
    1. Go to the Transaction, for which we want to find the BADI, take the example of Transaction VD02. Click on System->Status. Double click on the program name. Once inside the program search for ‘CL_EXITHANDLER=>GET_INSTANCE’.
    Make sure the radio button “In main program” is checked. A list of all the programs with call to the BADI’s will be listed.
    The export parameter ‘EXIT_NAME’ for the method GET_INSTANCE of class CL_EXITHANDLER will have the user exit assigned to it. The changing parameter ‘INSTANCE’ will have the interface assigned to it. Double click on the method to enter the source code.Definition of Instance would give you the Interface name.
    2. Start transaction ST05 (Performance Analysis).
    Set flag field "Buffer trace"
    Remark: We need to trace also the buffer calls, because BADI database tables are buffered. (Especially view V_EXT_IMP and V_EXT_ACT)
    Push the button "Activate Trace". Start transaction VA02 in a new GUI session. Go back to the Performance trace session.
    Push the button "Deactivate Trace".
    Push the button "Display Trace".
    The popup screen "Set Restrictions for Displaying Trace" appears.
    Now, filter the trace on Objects:
    • V_EXT_IMP
    • V_EXT_ACT
    Push button "Multiple selections" button behind field Objects
    Fill: V_EXT_IMP and V_EXT_ACT
    All the interface class names of view V_EXT_IMP start with IF_EX_. This is the standard SAP prefix for BADI class interfaces. The BADI name is after the IF_EX_.
    So the BADI name of IF_EX_CUSTOMER_ADD_DATA is CUSTOMER_ADD_DATA
    3. Go to “Maintain Transaction” (TCODE- SE93).
    Enter the Transaction VD02 for which you want to find BADI.
    Click on the Display push buttons.
    Get the Package Name. (Package VS in this case)
    Go to TCode: SE84->Enhancements->Business Add-inns->Definition
    Enter the Package Name and Execute.
    Here you get a list of all the Enhancement BADI’s for the given package MB.

  • How to calculate rms voltage, rms current and frequency from real time data?

    Hello,
    I need to calculate the real time rms voltage, rms current and frequency of the received voltage and current graphs using visa read. Actually am trying to monitor the voltage and current parameters of AC load, in this case, am using a set of 4 light bulbs at the moment. Expected frequency is 50 Hz, and rms voltage close to 240v AC, current about 1A. 
    Attached is the vi picture of what I have been able to achieve so far, courtesy of labview forums. But I need to finally finish this vi by calculating the Vrms, Irms and frequecy. The front panel shows the voltage (Chart V) and current (Chart I) after scaling. Chart VI represents ADC value 0 ~ 1023 of received data. Aray V & I show the binary bits received up to 10 bits of useful data from ADC. Each sine wave from ADC is sampled at 25 samples for the ADC conversion, and sampling frequency of 1.28kH.
    I have tried using the RMS vi, but seems I don't know how to configure it correctly to get desired results. Also when I make changes like switching of one of the bulbs so that their is current change, I need to refresh the SERIAL port first before changes show up on the VI. Any ideas on how to improve on this are highly appreciated.
    Otherwise, I would appreciate if somebody helps me MODIFY my VI to read the rms values and frequency from received data. This is the last piece of my project, I do appreciate all the help rendered. Am currently using labview labview 2014, student version!
    Gavin.

    hello,
    note that peak voltage (Vpeak) is (240 * 1.414) = 399 V and peak current about 1.414 if intended rms current is 1A.

  • How can I save/write data on the hard disc of the Real-Time System?

    I would like to acquire huge size of data via LabView Real-Time System.
    Since data is so huge, I am now thinking that it might be good idea to
    write/save data on the hard disc of the Real-Time System first and then
    transfer the data file to a data processing PC using FTP etc.
    If you know how to save/write data on the hard disc of the Real-Time System
    (Ver. 7.1), please let me know.
    Thanks,

    Just to add to Aitortxo's good answer,
    Since you have only one Drive ( C:\) on your RT, just keep monitering the availible disc space.
    After every few set of file writes keep transferring Backups delete these files, so that you  keep C:\ drive space for running your applications.
