  At the time wherever you go for the beautiful diadram, you could have done the vi

  Your DAQ would like a waveform (table of values and dt ak 1/sampling rate)

• Positive and negative frequency of calculation deviation

  Hello

  IAM with PXI-5620 to measure RF PXI 5600.

  I need to measure the frequency deviation, Positive and negative. The example or vi "MT DAMA demodulate FM.vi" gives peak frequency deviation . Can any please help me find the positive frequency Deviation and negative frequency deviation of her

  Thank you

  Niju.

  Hi Johanna,.

  First things first - 5620 5600 + combined is what we call a PXI-5660 RF Signal Analyzer.

  The PXI-5660 module cannot be presence via the driver NOR-DAMA. The Modulation Toolkit FM sample that you reference is for the PXI-5661 and SMU-5663 analyzers, both use the driver NOR-DAMA.

  You use MT ni5660 FM demodulation. vi, located under the ni5660 examples.

  Now to your question...

  When you perform an FM demodulation, resulting the Subvi MT Demodulat FM data frequency / time with the frequency values (Y axis), is compared to the carrier frequency specified. Thus, data deviation of frequency (Hz), function of time. All you need to do to get the positive and negative frequency deviation is to use LabVIEW table Max & Min primitive functions of table palette. This will give you the min and max value of the FM data that will be the negative peak and the positive peak frequency deviation.

• SELECT statement: summing up a positive and negative value

  If I want to get the sum of the positive and negative values, can I do it like this?
  
  
  Negative:

  Select sum(amount) INTO negative_amt FROM order where amount like '%-%';

  Positive:
  

  Select sum(amount) INTO positive_amt FROM order where amount not like '%-%';

  If this is not the case, how should I go about this?

• angles, positive and negative area on a plot of polar

  Is there a way to label the sector on a polar plot angles with +/-values? We generate a lot of bosses of directivity of sonar and angles scored from-180 to 180 instead of 0 to 360 have long been the norm. Looking at the definition of the curve and Polar - display the tab - it doesn't seem to be an obvious way to do it.

  Hi Greg,.

  Unfortunately, there is no way to do in tiara at the moment. I presented a report of Corrective Action to resolve this (#323394), and I hope that this feature will be included in a future version of DIAdem. Thank you for that bring to our attention.

• Grid Y looking positive and negative in CS5

  I know there is another thread with discussion on why different programs the y axis upside-down, which is good.  The problem is that all the previous versions of Illustrator have your zero point as it would on a normal mathmatical grid.  Why now after 7 years of using Illustrator must I "Rethinking" how I move objects.  We create dielines and now if I put my text of the measure and captions on the top and bottom, to do the opposite of what we have done during all these years.  Besides the work placement.  Why is there not an option?  It's pathetic to from Adobe.  Someone please tell me there is an option to invert the y-axis now inverted.

  Monika said.

  Here it is:

  To change the origin of the rule in CS5 are the same as in CS4 and earlier versions, you can:

  (1) find and open the AIPrefs (Win talk) or Adobe Illustrator Prefs (Mac talk) of the file. It is a hidden file in the folder hidden settings of Adobe Illustrator CS5

  (2): find and replace the following two bits of code:

  /isRulerOriginTopLeft 1 > /isRulerOriginTopLeft 0 (replace the 1 with a 0)

  /isRulerIn4thQuad 1 > /isRulerIn4thQuad 0 (replace the 1 with a 0)

  Note: This is a global change.

• How do you know if there are more positive or negative numbers?

  I'll try to explain my problem with an example, because I do not have labVIEW installed in the computer.

  I have 10 numbers and multiply to 10 other numbers

  and of course I get 10 results, after I have to show the value of meddium of this 10 results and must show the signal that most seem (+ or-)

  My problem is to show the signal, if I have 7 positive 3 numbers and negative numbers, how to measure and display the negative signal to the final?

  example:

  -0,3-0,8 1 0.3 0.6-0.7 - 0.1-0.5 0.3-0.4

  If I have to put in the final:

  -0.5

  Thank you

• How to make a text field to accept a capital letter has or a number in the position of the first character and only the numbers after that?

  Hi all

  We have a text field in one of our screen in our mobile app. Currently the user can enter alpha numeric characters in this text field.

  It is now that this field should accept a capital letter A or a number in the position of the first character and only the numbers after that.

  Could someone let us know how to do this?

  Thank you.

  Or, how about the substitution of this abstract method in textFilter?

• How to set the position and size of the façade using the FPRunTimePosRunCustom method in a c# application?

  How to set the position and size of the façade using the FPRunTimePosRunCustom method in a c# application?

  I found a solution! -Set the size and position of the façade with the help of the

  File > VI properties > window running Position (in category list) > custom (in position of menu drop-down).

  then just accept the current position and size (leave the boxes checked) or set values you want directly (uncheck the boxes and fill in the numbers), or physically position and size the façade and use, the "set to current location" button and press "set size" current All that is easier for you.

  OK so it does not make use of the method VI Methods (Active X) FPRunTimePosRunCustom ([Position], [Size]) but if labview want to make him difficult to use then other means must be found.

• Absolute position and orientation of the camera

  Hey folks, I'm banging my head against the wall trying to figure what I think should be a fairly simple expression.

  I'm trying to get my camera to an animatic of a moderator move offshore, and is not imported correctly on its system at least that the camera is not related to what whether in sequels.

  So, my relatively simple (I thought) solution was to use the term toWorld on a new camera to watch the old one and generate the absolute position and X, Y, Z rotation.  However, nothing I do seems to put the new camera in the right place, and I can't figure out how to make the rotation of key frames work not at all.

  Little information about the project, the camera has separate X, Y and Z position keyframes and rotation keyframes X and Y as well as Orientation (although I want the final device to have X, Y Z rotation keyframes).  The camera is related to a null value which has alterations Y rotation.

  If anyone can help me to collect these expressions I would be so grateful!  Thank you!

  See if this helps:

  position

  C = thisComp.layer ("camera 1");

  C.toWorld ([0,0,0])

  point of interest

  C = thisComp.layer ("camera 1");

  C.toWorld (C.pointOfInterest)

  orientation

  C = thisComp.layer ("camera 1");

  u = C.toWorldVec ([1,0,0]);

  v = C.toWorldVec ([0,1,0]);

  w = C.toWorldVec ([0,0,1]);

  SINB = clamp (w [0], 1, -1);

  b = Math.asin (sinb);

  co. = Math.cos (b);

  If (Math.abs (co.) >. 0005) {}

  c = - Math.atan2 (v [0], u [0]);

  a = - Math.atan2 (w [1], w [2]);

  } else {}

  a = (sinb< 0 ="" -1="" :="">

  c = 0;

• iTunes 12.5.1.21 not remember iTunes position and size

  Update iTunes 12.5.1.21.

  Win 10 (v1607) does NOT remember iTunes position and size.

  My system uses two monitors with extended desktop. I would like to put iTunes on the 2 left / top of the page. But after the closure and revival, iTunes always appears in the center of the screen 1 and the original size when updating. She also can't remember the last page of the articles that appeared, for example, Podcasts, applications, etc. When iTunes has been closed. Instead always defaults to the page music.

  Also on launch a screen "Welcome" iTunes with No thanks / OK buttons on bottom is displayed momentarily before displaying the page of music. There is not enough time to read what this screen offers. Looked in the menus to try to find this page to display... no luck.

  Anyone else having these issues?

  Same problem here.  Very annoying.  Each time is like the first time, which is great when you talk about sex, but not when you run iTunes.  All versions up to now has been able to hold its window size and position, but not anymore.  I also find the interface is very slow to boot.
