How can I use USRP as a noise generator?

Hi everyone.
Does anyone know how can I use a NI USRP 2920 to generate white noise or impulsive noise at its Tx port?
(I am kind of new to this area and any help is appreciated)
Thanks.

Hello,
I am assuming you are using LabVIEW to do this, correct? DO you have access to the help documentation for the NI-USRP driver? Within the help document there is a section called Software Fundamentals which has a section within it called NI-USRP Instrument Driver Programming Flow. This section shows you how to set up the USRP to transmit a signal. The default case is for an arbitrary array of data to be supplied to the Write Tx Data function. Instead you could use the output from the Uniform White Noise VI as the input for the Write Tx Data function. This should write the the white noise to the output of the USRP.
NI-USRP Instrument Driver Programming Flow:

Uniform White Noise VI:
http://zone.ni.com/reference/en-XX/help/371361H-01/lvanls/uniform_white_noise/
I hope this helps.
Thanks,

How can I use the presets which were generated in Bridge (CS5) so I can use them in Lightroom 4

I currently have 30 + presets which I have generated in Bridge and when I open the same photograph in Lightroom 4 it appears that the inform from the preset has not come across bridge to appear in lightroom. What have I done wrong or missed?
Thanks for your assistance
Peter

If you read the metadata from the file into Lightroom you can then use that file's metadata to create a Lightroom Metadata preset.
You'll have to do it uniquely for each of your 30 presets but presumably still quicker than creating LR presets from scratch.
And probably best to do it on dummy files and check you've only got the metadata you want before saving it as a new preset..(or at least before applying the newly created preset.to many, many files!)

How can I use the speakers from my old iMac (with miniRCA? plug) on a new iMac

How can I use the speakers (M-Audio) from my old 24" iMac on a new 27" iMac? There is no jack on the new iMac - is there an adapter that will use the mini-RCA (?) plug from my old speakers to connect them to a new iMac? Thanks ...

Thanks again!
Hmmm ... I wonder. The input jack for external speakers quit working on my old iMac (it made lotsa static noise for a while when I moved the plug or computer, then quit working completely; I figure something inside the computer got loose or crapped out - and I'm too cheap/lazy to take it the 20 miles to the nearest shop that might fix it). When I plug the speakers into the headphone jack on the old iMac, I get very low volume or just one channel.
I don't have the new iMac yet, but I was hoping to use these old speakers instead of buying new ones. I will certainly try your solution - what do I have to lose? If they don't work, then I get new ones - or try something else.
Many thanks for your time!

How can I use 2 Apple IDs in Itunes? I have 2 IOS Devices. They each have there own AppleID. What is the proper way to sync both of them to Itunes?

How can I use 2 Apple IDs in Itunes? I have 2 IOS Devices. They each have there own AppleID. What is the proper way to sync both of them to Itunes? I wanted my teenager's AppleID to be different from mine so that she couldn't charge stuff to my AppleID, therefore I created me another one. Now when I go to Sync either device, it tells me that this IOS device can only be synced with one AppleID. Then I get a message to erase it, not going to do that, lol. If I logout as one ID and login as the other, will it still retain all synced information on the PC from the first IOS device? If I can just log in out of the AppleID, then I have no problem doing that as long as the synced apps, music, etc stays there for both. I am not trying to copy from one to the other, just want to make sure I have a backup for the UhOh times. If logging in and out on the same PC of multiple AppleIDs is acceptible then I need to be able to authorize the PC for both devices. Thanks for the help. I am new to the iOS world.

"Method Three
Create a separate iTunes library for each device. Note:It is important that you make a new iTunes Library file. Do not justmake a copy of your existing iTunes Library file. If iTunes is open,quit it.
This one may work. I searched and searched on the website for something like this, I guess I just didn't search correctly, lol. I will give this a try later. My daughter is not be back for a few weekends, therefore I will have to try the Method 3 when she comes back for the weekend again. "
I forgot to mention that she has a PC at her house that she also syncs to. Would this cause a problem. I am already getting that pop up saying that the iPod is synced to another library (even though she is signed in with her Apple ID to iTunes) and gives the pop up to Cancel, Erase & Sync, or Transfer Purchases. My question arose because she clicked on "Erase & Sync" by mistake when she plugged the iPod to her PC the first time. When the iPod was purchased and setup, it was synced to my PC first. When she went home, she hooked it up to her PC and then she erased it by accident. I was able to restore all the missing stuff yesterday using my PC. However, even after doing that it still told me the next time I hooked it up last night that the iPod was currently synced with a different library. Hopefully, you can help me understand all this. She wants to sync her iPod and also backup her iPod at both places. Both PCs have been authorised. Thanks

If you are just visiting Singapore, then leave the account as it is. If you have moved there, then view your account using the iTunes app on a Mac or PC and change the country/region to your current location and address. If you do not have a bank card, you can fund your account using iTunes gift cards if available in Singapore.

How can i use microsoft word on ipad 2

how can i use the microsoft application on my ipad 2?

The Pages app is also compatible with MS Word. Unlike some of the others mentioned, the document is actually stored on the iPad as opposed to 'the clouds'. Again, most of those mentioned are cut down versions of MS Word.
Stand back and look at this constructively; do you need to regularly access to the document from more than one computer/device without the need to keep amending your document on your computer and sending it to your iPad? If so, Documente to Go etc may be the best choice.

How can I use the credit on my account instead of credit card to buy apps?

I have a gift card credit on my account but when I want to buy an app it takes me to my credit card details. How can I use my credit on my account instead of credit card?

You shouldn't have to put in a credit card, no, but from time to time the iTunes Store seems for some reason to try to insist on one. If just confirming your mailing address doesn't stop it from complaining, go here:
http://www.apple.com/support/itunes/contact/
and follow the instructions to report the issue to the iTunes Store.

How can i use one SQL statement to solve problem?

How can i use one SQL statement to solve the question below?
For a Table named A, there is a column named F(char type).
Now select all the records where F like '%00' and update their F value to '%01'
Just one SQL statement.Do not use PL/SQL block.
How to do that?
Thanks.

What is the data volume for this table?
Do you expect lots of rows to have '%00' as their value?
Following two statements come to mind. Other experts would be able to provide better alternatives:
If you have index on SUBSTR(f, 2):
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) || '01'
WHERE substr(f,
              -2) = '00';If most of the rows have pattern '%00':
UPDATE A
SET    f = SUBSTR(f,
                  1,
                  length(f) - 2) ||
           DECODE(SUBSTR(f,
                         -2),
                  '00',
                  '01',
                  SUBSTR(f,
                         -2));

It is not possible to create a new iCloud account using a Windows machine. You must create the account using a Mac (10.7.5 or more) or an IOS device (iPhone etc). Once that is done you can sign into and use the account on your Windows machine.

How can I use home sharing between our iphones (create playlists from both accounts at once)

How can I use home sharing between our iphones, so that we can create playlists with songs from both of our libraries? We share a Macbook Pro (separate accounts) and each have the new iphone, but when I have my iphone and try to create a new playlist, I can only grab songs from one account. Is there a way to create a playlist using both accounts since we are sharing?
Does it have to be created within iTunes first on our Mac?

The short answer: because Home Sharing isn't designed for sharing apps, and apps aren't designed to be shared.
The longer answer: Think of it like this...
You download some music in iTunes. With Home Sharing, another user can listen to it by streaming it over the network. But the data itself is on your computer. If you turn off the computer or take it off the network, the other user can't access it.
But if you send another user the app, they aren't just streaming the data- they installed it on their iOS device. Because they weren't the one that purchased it, such a transfer could easily be considered "piracy" or "stealing," and nobody likes that (least of all, Apple).
When iTunes sees this app, it obviously recognized it, as if saying, "Hey, how did you get this app on your device, if I have no record of you purchasing/downloading it from the iTunes store?"
