• 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.

• positive and negative rotation numbers

  Hi all

  I create a roulette game that calculates the winning number based on the rotation of the main wheel. I'm if/else using statements to determine the winning number based on the rotation. I am tracking the rotation in the output panel. I want my rotation to go between 0 and 360, but the output panel trace 0-180, then it starts from "-180-0."

  The wheel can turn several times. No idea how to keep the positive numbers between 0 and 360, and do not have to write my if else to accommodate negative numbers?

  Thank you!

  var rot: Number = (whatever._rotation+360)%360;

• the combination of two select statements to increase the maintainability and performance

  Hi SQL Experts,

  I use the Version of Oracle 11g DB and got both of the statements below.

  My mind can´t get his head around it how and if these two can be combined.

  They look like they could, but I can't figure out how... and I don't mean with a UNION ALL operation

  My main goal is a gain in performance and maintainability.

  SELECT *.

  OF T_TEMP_42 T1 WHERE T1. MATRIX_2 IS NULL AND

  (T1. BL_CODE | T1. YASSINE | T1. MATRIX_1 | T1. FIRMTYPE)

  PO NO

  (

  SELECT BL_CODE. YASSINE | MATRIX_1 | FIRMTYPE

  OF T_TEMP_41, WHERE MATRIX_2 IS NULL).

  ------------------------------------------------------------------------------------

  SELECT *.

  OF T_TEMP_42 T1 WHERE T1. MATRIX_2 IS NOT NULL AND

  (T1. BL_CODE | T1. YASSINE | T1. MATRIX_1 | T1. MATRIX_2 | T1. FIRMTYPE)

  PO NO

  (

  SELECT BL_CODE. YASSINE | MATRIX_1 | MATRIX_2 | FIRMTYPE

  OF T_TEMP_41, WHERE MATRIX_2 IS NOT NULL

  );

  Thanks for your suggestions.

  Try this

  SELECT *.

  OF T_TEMP_42 T1

  WHERE (BL_CODE, YASSINE, MATRIX_1, FIRMTYPE, MATRIX_2) NOT IN (SELECT BL_CODE, YASSINE, MATRIX_1, FIRMTYPE, T_TEMP_41 MATRIX_2)

  It came off really simple... maybe too simple

• 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.

• Select the last Date of multicolumn and its value adjustent cust_id

  I have a Table with 5 customer_id and 5 Dates with each belonging to its cust_id.

  I need to take the last, in my example would be CUSTID_5.  I know

  this with the GREATEST who select the CHANGE_DATE_5 (in my example), but

  How to choose the CUSTID_x? that goes along with the winning Date?

  create table test_tbl)

  number of custid_1

  date of change_date_1,

  number of custid_2

  date of change_date_2,

  number of custid_3

  date of change_date_3,

  date of change_date_4,

  number of custid_5

  date of change_date_5

  );

  INSERT INTO test_tbl

  (CUSTID_1, CHANGE_DATE_1, CUSTID_2, CHANGE_DATE_2, CUSTID_3, CHANGE_DATE_3, CUSTID_4, CHANGE_DATE_4, CUSTID_5, CHANGE_DATE_5)

  VALUES

  (111, sysdate, 222, sysdate + 1, 333, sysdate + 2, 444, sysdate + 3, 555, sysdate + 4);

  commit;

  Hello

  Here's one way:

  WITH unpivoted_data AS

  (

  SELECT custid, change_date

  , EVALUATE () OVER (ORDER BY change_date DESC) AS r_num

  OF test_tbl

  UNPIVOT ((custid, change_date)

  Label ((custid_1, change_date_1) AS 1)

  , (custid_2, change_date_2) AS 2

  , (custid_3, change_date_3) AS 3

  , (custid_4, change_date_4) AS 4

  , (custid_5, change_date_5) AS 5

  )

  )

  )

  SELECT custid, change_date

  Of unpivoted_data

  WHERE r_num = 1

  ;

  Having several columns for several occurrences of basically the same thing is a bad table.  This problem would be much simpler, but also more effective if each pair custid/change_date has been strored on a separate line.  In addition, you would not be limited to 5 pairs.

• remove the negative values in table

  I have a table 1 d of data depending on the positive and negative values. I'm trying to search for negative values and remove them from the table.  This corresponds to the data in the column in the second table 2D that should also be deleted. A minor problem is that there are an additional column in the 2D array that must be skipped.  I have the code that should do it.  The problem is that if I have two negative numbers in a row the code doesn't thow on the other.

  This first picture is the answer I get when alternate positive and negative values.  It shows the correct answer.

  

  When I change the first1 of the positive a-1 value as shown below...

  

  ... I get the following response.

  

  FYI, some other things such as conversion are here because I'm trying to manipulate the actual data set is enormous.  I test everything I do with the numbers that I can actually follow before I apply in my real program.  That's why I do extra things.

  Thanks for the help!

  Here is the solution, that increase the index when you do not remove an element. In addition, whether you use the "less then or equal" when you use the "lower to."

  

• can we write the function in a select statement?

  I have function and there Out parameter, so in this case I can write a select statement to my function to retrieve the value?

  user11195165 wrote:

  Never mind that it's bad! for a function to have an OUT parameter. That's not how the functions should be designed and written.

  It's like with a knife like a spoon to eat porridge. Of course, it can work in a way. But why? A knife was never designed to be a spoon - and while it may work of porridge to eat, you'll have a hell of a time trying to use it to eat the soup. So, use the right tool.

  In other words, a function is the wrong tool for the job. Use a procedure.

• How can I do to two clips have the same position and scale?

  I just first Elements 10 today, since I'm doing a video for work. I am a seasoned videographer (I am a fairly successful YouTuber), but not with Adobe products. At home, I use Cyberlink PowerDirector 13 (although that is seriously considering moving to Premiere Pro), but for the moment at work I use elements since it is the program that they have.

  One thing that elements can do that PowerDirector is automatically align the clips at the same time. What I need to do, it's got a picture (do not fill the entire screen) suddenly cut to a similar picture of the same size and position, of the effect that the only part of the image changes. In my program to another, all I had to do was put them at the same time, change the shape of the Pic 1 how I want it, move the 2 Pic and do align on the same size and position, then move 2 peak after another in the timeline panel. However, items not the snap to each other, so I have no idea how to put them in the same size and position, one after the other.

  How can I do this? If this can be done in two elements or Pro, I'm going to have to Pro since I use this feature a lot.

  Thanks in advance!

  First Elements 10 on what operating system? What video/graphics card your computer use? If NVIDIA GeForce, so we talk 10/NVIDIA GeForce display and other problems related specifically to first Elements.

  But, so far away that...

  Each clip on the Timeline of 10 elements first has a range of properties that contains a sign of movement. The expanded Motion Panel includes settings for the clip Position and scale. among other things.

  Position of two values... (___) (_) first from right to left and from left to right... second for up down or down the most.

  Have you been to the Palette of the 2nd clip properties to set its Position and scale values must match the first element?

  Have you been there and done that?

  Please read and review, and so let me know if I've targeted to what asked you. If this isn't the case, please specify where I missed what you were looking for.

  We'll rethink the situation if necessary and provide screenshots if necessary.

  Thank you.

• Negative value to run to analyze the report in the statspack report

  Hello
  
  I use Oracle 10.2.0.3.
  
  In the Execute to analyze the value of its pack stats report report, I get the negative value-35%. I read that this means that there are more number of parse as executions. But how and where it can be checked off, and what step I can take to resolve/correct this?

  I have a procedure 'a' who calls the procedure b, c and d in it.

  I have a table "t" that is referenced in the proceedings b, c and d (not in one)

  I've run a DDL on the table "t" where, by b, c and d invalid and in which cases invalidate the procedure as well.

  I call the procedure 'a' for execution, but in this procedure, I circumvent enforcement of procedures b, c and d (I can do this based on a condition and I don't call these procedures during execution of the procedure a).

  Then, when I call the procedure, it will be recompiled, but before he could be recompiled, oracle has recompile b, c and d as well.

  So in this case, I don't have that a single execution of procedure 'a' but compilation of a, b, c and d have run to analyze the ratio of 1:4.

  I hope you understand now. Which is why I suspect me that your procedures are be invalidated yet and still have several compilations.
