inialization vi produces scalar and 1 d vector input

I'm currently building a suppressor of adaptive noise (LMS type 11) as stated in a document of OR. I have a problem with the dot product vi. An input vector is an empty array, and of course the result is NaN. Its in a feedback loop, so I think that the vi should be initialized with zero.

My questions are:

How to convert a 1 d table to a 1 d vector?

How to initialize the VI?

The upper part of the vi is a loud singenerator and the lower part is the adaptive noise suppressor.

Hi Penguin,.

How the coefficients of the filter being updated without feedback?

There is a feedback: it is called shift register.

You view the output of the Adder on the edge of the while loop not connected

The output of the add function has a wire attached. And it is connected to a shift register. Did I mention registers before shift?

or just show you the initialization part?

I just cleaned your VI. I change all the features (by intention).

When you have problems to work with registers at offset, you should take the free online courses offered by NI LabVIEW beginners!

    Today an illustrator file with vector objects and fonts that I worked on the days looked pixelated when enlargement to more than 400%. I could not find the fix so I have started a new canvas, selected all my pixelated, pasted into a new canvas and all transferred file properly so I could continue to work with my vector elements again.  I was curious to know if anyone knows what does my vector elements change in pixel and how to fix it.  Thank you guys

    a case is,
    If my function returns only a single value, then I can use oracle 'create function' with the return type as types predefined as a whole, varchar2 etc?
    with regard to performance.

    With regard to this performance problem? And why now suddenly change the question to want to use a function to return data type number or string? How does this relate to PL/SQL to return a cursor now?

    A function can return scalar values, not scalar. A function may return atomic values (such as a unique number, or a non-scalar list of numbers). A function can return a complex data structure consisting of scalar values, not scalar.

    However, in PL/SQL function must NOT be used to read the lines of the database to cache lines in a memory of the server PL/SQL (PGA), then back to the client.

    He does not. It does not fit. It is too bloody dangerous to the overall health of the server as such code plays silly blighters with very expensive server memory.

    A PL/SQL function can also be used as guideline, returning data via expensive PGA, but via the SQL engine instead and using its slider interface (which allows output data to be "gradual" and not to return all data with a single copy of croustilleur mass of the call stack) directly. IT IS, HOWEVER, AN EXCEPTION. There is very rarely the need to make the functions PL/SQL pipeline table - and is often victims of abuse and bad demonstrated with examples of absurd code here.

    Hello tooblackish

    Welcome to the Forums of the BlackBerry Support

    Sorry for the trouble, but I noticed this same problem with few other users, who could not send pings to any BlackBerry 10 there BlackBerry 7 devices.

    To solve your problem, I suggest to re-install BlackBerry Messenger!  To do this on your homescreen go to Options > device > application > locate and remove BlackBerry Messenger from there. After deleting to do a battery pull reboot as this device powered on remove the battery wait a min. then reinsert back.

    KB10040  : How to display or remove installed application on a blackberry smartphone   

     

    Finally, after the reboot, use your BlackBerry browser and go to www.blackberry.com/bbmdownload and download the latest available for your phone model. If device reboot prompt do then sign in with your ID BlackBerry even.

    Try it and tell us how it goes.

    _______________________________________________

    Please note:

    If you encounter BBM7 or higher then your BBM Contacts are integrated into your BlackBerry ID after installation when you log in with your BlackBerry ID Contacts is restored back, but if you experience any previous Kathy then first make a backup local, you can save on your press card, see this KB for additional assistance

  • Problem with keyboard: type 't' produced 't5' and typing 'y' produces "y6" after the computer error.

    computer laptop dv6700 left in the bag back for about an hour. When I discovered the laptop, it's on, but the screen is blank. After restarting the computer beeps three times, but wouldn't start. I tried to bring the computer several times up getting only beeps. The next day, the computer works fine except when type the characters 't' and 'y '. When you type 't' 't5' letters come and type 'y' "y6" when rises. Nothing has been poured into the laptop. I suspect that it overheated. Thanks for the help.

    Hello

    It seems mechanical mistakes here since all 4 characters are close together. The first thing I would check to see something such as metal, wet... or even a piece of something is sitting under these keys. The second thing, I would check to see any damage to the power cable under the keyboard. The next book you shows how to remove the keyboard and then put it back:

  • How to write constantly to analog output and read from analog inputs

    Hi all -

    I had a question about writing continuously to analog output reading simultaneously an analog input.

    It's my first time to post a message to the community, so please let me know if I made mistakes.

    I use Labview 2011 with a NEITHER-DAQ USB 6215.

    I'm looking to generate a waveform and write it continuously in an analog output. It is then connected to an entry on the acquisition of data, where I am trying to sample the analog signal. (I realize, there is a system of trivial, but I'm hoping to build on it once I have run).

    The task of reading from the analog input works fine, as I tested it in several other cases. I have a problem writing to the analog output.

    For this task, I tried to follow the "Gen Cont Wfm Clck Int' VI to generate the wave form and start the task. I then try to write to the output of the analog timed loop. However, it does not seem to transmit a signal and doesn't give me any errors.

    I have attached the VI but also a screenshot.

    Please let me know if anyone has any ideas. I would really appreciate the help!

    Thank you

    Peter Borgstrom

    We will review your tasks one at a time.  First of all, the task of generation/Analog output Waveform.  Generate you a waveform (I'm unsure of your VI if it is a fixed waveform or not) and send it to a defined output function to produce a waveform continuously, using N-channel and samples of N (where you set not these previously).  You should not put this inside has timed loop, as the DAQ hardware has its own clock - if you simply put it in a while loop (with a stop to break out of the loop), the loop will call the function for the first points of N, wait until all N have been taken out, then call it again to another N points (up to what you press Stop).

    Now, suppose that you have the output connected to a load voltage (say a decent resistance).  You can wire the input terminals of your A/D converter through the same load and set up a similar analog input loop, running in parallel (i.e. in its own independent of the OD loop, while loop).  You pourriez start together (with, say, a merged error since the initialization code line loops HAVE and AO become lines of error in "loops of sampling" described above), but you might want to delay loop (a little) the AI so that the OD has a chance to set the voltage before the bed.

    I hope this helps.

  • Pavilion15-p018nz: Windows logon screen does not display the symbol of 'the eye' to reveal a password and the right arrow (input)

    Which connection to Windows 8.1 the eye symbol and the symbol of the arrow to the right were posted up to that (I think so) after an automatic update of Windows. As I was intending to migrate to Windows 10 I na not invest a lot of research on this problem. Now, after the migration successful Windows 10 Home the problem still exists. After typing the password I can't check it out because the eye symbol is still missing and I have to press 'Enter' because of the clickable right arrow missing for the opening. All this happens with a Microsoft online account. I created an account local and with that, the symbol of the eye, but not the right arrow reappeared. Thanks a lot for help.

    Hi there @CKURT

    Welcome to the Forums of HP Support! It's a good place to find the help you need, so many other users, the HP experts and other members of the support staff. I understand that you want to activate the icon reveal password for your system. I'm happy to help you.

    It depends really on what version of the operating system you are running, because this kind of thing is normally controlled by using the Group Policy Editor. This tool is not a part of a home edition, you need the Pro version or later version for that.

    Assuming that you do not have a pro edition or higher, then it can be a help to you:

  • Retrigger encoder and acquisition of analog input on the spur of Z?

    I have a card PCI-6232 and use THIS angular Encoder on the counter 1 to provide a base mean angle for Internet high speed (50-100 kHz) measures the analog voltage.  I use a period of CI on counter 2 to measure the duration of the impulse of Z to determine the length of each measure.  It kinda works, but the result is somewhat contradictory.  I get about 1 in three cycles without encoder data.  I need to find a way to trigger the acquisition to record data for each cycle trigger on the pulse of Z.  If you know another way to do this I'd be open to that as well.  Thank you, Steve

    Hi Sara,.

    Thanks for your reply.  What I wanted to do was to trigger an analysis of the encoder and an entry at the same time triggering the pulse of z analog encoder.  It took a lot of digging through similar samples and after a week of fighting, I thought about it tonight.  I'll post this once I clean up the mess.  Problem solved thanks to dozens of you ad info and samples!
