How can I extract the frequency of the FFT function?
How can I extract the frequency of the FFT function in labview? Thanks in advance
If you have the f0 and df, you can find your frequency as you would find the time with a waveform based on t0 and dt. You just need the index of the data point in that you want to get the frequency. The frequency is then f0 + x * FD, where x is the index of the data point you are interested in.

Thank you for the review of this post. I appreciate any help you can provide.
I recently bought a new win 7. My tech copied all my old data from the previous machine to a single folder on my new machine.
I have a few Palm data... But it has not imported the TX model will not be installed on my Win 7 machine, so I have to achieve this through Palm Desktop. (I have read that could be caused by the fact that I went to version 6 of the palm software and tried to import).
Quite simply, here's my problem: I just want to really get my calendar information. I'll probably use a program different schedule in the near future.
How can I extract the data from the calendar since raw files? (Calendar.dat, etc.) ???
I have TO import or somehow go through the Palm software, or is it possible outside of Palm?
I THINK that this cannot be something too difficult, but I am so stuck and missing an appointment every day.
I am very grateful for your help.

With the version of the data files you have, you will need to install Palm Desktop 4.1.4e or 4.2. You will need to uninstall Palm Desktop 6.2, if that's what you have installed currently. With the .dat extension files are not compatible with PD 6.2.
Another thing to consider is the Win7 version you have installed. If you have the 64-bit version, you will only be able to sync wireless using bluetooth, infrared, or wi - fi. On your PC, go to the computer icon and right-click. Look at the page and see if it says 64 bit any where. If you have the 32-bit version, you can synchronize via USB cable method, but you must ensure that you have the correct version of installed PD.
In PD .dat files, you will need to go to the folder of user name on the drive of the program and paste the files in the appropriate subfolder. Make sure that the PD is closed. Go to c-program files-palm and find the folder user of PD. Once you find the file, search for the subfolders of this folder for address (this is the contacts folder), calendar (calendar), memos, and tasks. Paste the address.xxx files in the folder of the address, the file datebook.xxx in the folder of the agenda, etc.. Once the files in the respective locations, open PD and see if the data is there. If this is the case, you can then set the synchronization according to your version of Win7, either wireless or USB.
I want to extract the year of a parameter.
I tried the following, I make mistakes.
When I run the code below,
SELECT TO_CHAR(:X_PRM_YR_END_DT,'YYYY') FROM dual;
I got the following error.
When I run the code below,
SELECT TO_DATE(:X_PRM_YR_END_DT,'YYYY') FROM dual;
SELECT to_char (TO_DATE (: X_PRM_YR_END_DT, "YYYY")) FROM dual;
I got the following error.
ORA-01830: date format end before you convert all of the input string
When I run the code below,
SELECT extract (YEAR FROM: X_PRM_YR_END_DT) FROM dual;
SELECT extract (YEAR FROM 01/11/2013) FROM dual;
I got the following error.
ORA-30076: invalid field extracted from source

I have a question about the order of execution. In the WHILE loop, I have two things to measure, period and tension using the DAQmx READ functions for voltage and the meter. In the end, I want to collect these data as points almost simultaneously as possible, as a pair and then send them together to another piece of code (not shown here) which them will result in some sort of command for an engine. It would be run, and then I want to perceive the tension and the period at a time later and do the same thing.
(1.) I'm a little confused on what the meter of the READ function is back because it's a table. What is a picture of? I thought that it was up to the value of the individual periods between rising edges. The output of the counter 1 DBL d's a table. How many elements in this table, and what determines the size of this table? Are the elements of the array the individual delays between the edges? How many values are stored in the array by executing? We take the AVERAGE of the last 15 items, but do not know if we are throwing some of the data or what. How to understand the composition of this painting? How can I change the composition of this painting? Is it possible to measure only one period at a time, for example the time between TWO edges?
2.) Will this WHILE loop execute as it gathers tension and a "period table ' (remains to be understood by me) by TIME running in a loop? In particular, we want that the value of the tension associated with the value of the AVERAGE of the period "array", so we can use two data items to create orders of next control every time that the two values are reported. The structure for the delivery of vi will be attached data in pairs like this? I understand that one of the READING functions run not before the other function of READING in the WHILE loop. I want that the period "means" and "strain (Volt) collected at the same pace. This vi will he?
I suggest including the DAQmx Start Task function. If it does not start before the loop, it starts the loop and work very well, but it is not as fast and efficient. In the model of task status, task wiill go to run the checked each iteration of the loop and then back the time checked running when it restarts.

Usually, when I want to extract the msi file from the distribution of exe (for Group Policy) installation drive, I download from get.adobe.com/reader/enterprise and decompress the exe file using 7zip. Then I integrate the msp inside file and I'm pretty much good to go.
Now, when I try to extract the msi file, I get a directory full of stuff, but no msi at all. I tried the installer and watch in C:\users\username\AppData (it works for Java), but it wasn't there.
No idea what I am doing wrong? Or y at - it a new way to extract the msi file that I missed?

When I select shuffle songs, albums or playlists, my ipod continues to play the same song again and again. How can I mix between songs (it's the third ipod I had and it has always worked before)
There is a separate parameter called repeat (unrelated to the Shuffle setting). It can be set to Repeat OFF (no repeat) Repeat ALL (repeat current list) or Repeat ONE (repeat current song). I think you have to repeat the value Repeat ONE.
This setting is on screen Now Playing on the iPod to an iPod with a touch screen. Tap the screen to see repeat the setting button. It looks like two arrows in a loop. This time, it is probably blue with a little "1"; Tap change setting repeat (by blue without the '1' or not blue).

My laptop mouse pad is no longer scroll in FireFox or MS Word (or any other program I've tried) since switching from Vista to Windows 7. In the Windows Help section, it suggests that there should be a tab "Scrolling" in the mouse properties window, however, when I opened the window just 4 tabs are "Buttons," "Pointers," "Pointer Options" and "hardware". How can I switch on / activate the scrolling feature?

Ensure that the measure is not shaved base measure, and it is the measure of level of detail...

I use LabWindowsCVI8.5 and NI Vision to make the treatment of the Image. When I read the "IMAQ Vision for LabWindowsCVI Reference Manual", I found that the imaqBCGTransform function only supports 8-bit Image, while I do the BCG to turn on 16-bit image. Are there solutions to use the BCGTransform function to deal with the 16-bit Image? Or any other feature that could make the correction Gamma, contrast and brightness on the 16-bit Image?
Thank you very much!
because imaqBCGTransform is implemented as a lookup table, we can understand why it is limited to 8-bit images.
Now let's take a look at the definition of each of this mandate (from the NI Vision Concepts documentation):
-brightness: a constant added to the components red, green, and blue pixel of color over color, decoding of the process;
-contrast: a constant multiplication factor applied to the components of the luma and chroma of a pixel of color in color to decoding process.
-gamma correction: expand high gray-level information in an image while removing information of low level of gray. (the chapter on lookup tables gives some examples of corrections gamma)
now that you understand that this transformation is a simple mathematical function, simply calculate the correction for each pixel on your 16-bit images.
I know not the exact formula used by the imaqBCGTransform function, but you should be able to approach by performing some tests on images 8 bits with the original function... or you can make your own formula... or find one on the net... or you can ask someone at home OR you give the formula...

I am trying edition 35 shoots blocking of 10 minutes. Most of them worked very well. Videos synced to the top just fine. This feature of love! On about 4 of them, the audio does not sync... Although it is the same audio... but I can't get the videos to sync using in and out of the points. When I use and points, it synchronizes the, but the videos are mixed and not even closed to where I put the entry points and. I almost killed myself trying different things to solve this problem on a few clips that I left. Please help me understand this.
The more safe bet when automatic synchronization is not working is to go old-school:
- Create a new sequence.
- Insert the clips are stacked on separate tracks
- Synchronize them manually.
- Nest of this sequence in another new sequence.
- Right-click on the nested sequence, open the submenu multi-cameras and click Activate.
You are now ready to change this as a multicam sequence.
Now, as to why the audio synchronization does not work... First, there are cases that the first algorithm can't handle; for those, you may need to use a program like PluralEyes. Sorry, I'm not an authority on which cases are known to be problematic. If yours is a case that the ORGANIZATION must be able to handle, one possibility is the order in which you selected clips. At least some users have reported that this makes all the difference. See Post #10 here: http://forums.adobe.com/message/5945016#5945016. As I note here, a fix came into CC7.2 for a problem in this regard.
