Conversion of waveform (DBL) in table 1 of double d

Similar Questions

• 1 table D of waveform DBL file or its

  Hello.

  I am building an application where I have an accelerometer with an interface USB-1208FS samples.

  I have this loop on the inside with a few virtual instruments to display the waveform and frequency of it components. I tried many different approaches to record in a file, but it doesn't seem to work. No file is created even although I am administrator.

  Data that are fed to the filters and these great are "table 1 d of waveform (DBL). Tried to convert other types of data, but does not work. This VI for example 'write waveform of File.VI' does nothing even if it should accept this type of data. It's "waveform table is a 1 d table the you want to write to a file of wave forms.»

  I'd appreciate any help on my way to accomplish this task. With regard to Abraham

  You still have not posted this VI. You say exactly what function and it is inside the loop / out of the loop that wants to say? My only guess is that you use the button stop in the toolbar.

• Table to convert 1 d of waveform (DBL); Convert the table to a 1 d of waveform (LDM)

  Hola a todos soy nuevo in LabVIEW asi os ruego patience, mi duda're basica y annoyingly, como hago para convert a table 1 d in una Forma Onda 'Waveform (DBL)', os editor una imagen y mi VI, Gracias.

  Hi all, I am new to using LabVIEW, so I beg you patience, my question is basic and simple, how to convert an array of 1 d in a waveform (DBL), thank you

  Table of index

  In my view, that the sound VI gives you a waveform for the right channel and one for the left.  For example, you may have to play with the index to determine which channel you want.

• Convert the waveform (DBL) to a cluster of 2 elements

  Hello

  Can someone help me to convert the data type of waveform (DBL) to a cluster of 2 elements (X, Y). I found a few examples online, but I get an error when I wire everything together. I use VI of Tektronix to acquire a signal of channel 2 of my noculars, which I am able to do, but now I want to convert this data to a cluster so that I can use it for an existing application to acquisition. I have attached my VI version 8.2.

  1Thanks

  The is easy since it is part of the waveform data type.  The X, you will need to calculate based on the dt by using a loop FOR.

  

• waveform compared with table 1 d of waveform for a Subvi connection

  Hello

  I have a Subvi I change so it can accept an entry of type of waveform (it used to take a double 2D array). I created the type indicator 'waveform' on the front of the Subvi and connected according to terminal diagram. However, the block of acquisition DAQmx I need to connect (from the parent company VI) generates a table 1 d of waveform, and that's why it the two are not compatible. Can someone tell me please how to make the indicator in a table 1 d the type of waveform, rather than just a type of waveform?

  Thank you
  Claire.

  Place a container on the front table, drop the control of waveform inside and connect to the connector pane. See how far you get.

• PeakDetector on top of waveform DBL

  I have a waveform DBL I want to find the vertices. I have the feed in the PeakDetector, but cannot figure out how to place the output of the peakdetector on the same plot in the form of wave DBL. At the end of the day, I want data peakdetector to output to a data file with the same time-domain in the form of wave DBL.

  Here is a picture of the current situation.

  Thank you!

  Hello

  You can use the XY graph to plot locations detected PEAK and waveform input.

  Please see the code.

• How to extract data from digital 1 d or 2D waveforms in a table or excel file?

  Hi all

  My DAQ gives me data in the form of a table 1 d or 2D-waverform digital time.

  How to export the data in an excel file or copy it into a table?

  Hi Prasanth,

  Some options come to mind:

  -pass the DAQmxRead to give you fair DBL tables instead of waveforms

  -use a conversion like this:

  

  -use functions of PDM, they accept waveforms...

• How convert the waveform on the table of waveform waving on waveform graph

  Please answer now...

  Your other post indicates it is a thesis, I consider homework. What did you do? What do you mean? What do you get a waveform graph? You have one, or the plots of 10? If you have a parcel, what you get as the data type for the data in the chart? If you have more than one conspiracy, what do you get? What is the data type that accepts a waveform graph? Have you looked to see how that is defined?

  For example, let's say you have a parcel on your chart. When you get the data, you get... a table 1 d of values. It's kind of logic, right? Well, what is the type of waveform data? It consists of a starting point, time delta between points and an array of values. Hmmmm... So, what about using the wave function of build? Just a thought...

• Conversion with conditional text in table

  I take the first steps in converting unstructured structure image. A single document is fairly clean except for one question: my structure breaks around conditional text in tables. (The tables have a their own, but the conditional text questions f3ew seems to make the problem worse) I don't know how it should be treated. Structure tags are displayed in the view below.

  

  And here's the view of the Structure:

  

  Is this something that can be implemented with a qualifier, and if so, how? In addition, in the mapping of conversion table, is there any dependency order, as well, on which appears the conditional text element?

  Martine

  As Michael says, a conversion table does not convert the structure conditions. In a structured document, we apply, removes, shows and hides the conditions in the same way as is done on an informal document. The only difference is that you can select entire items and treat them with conditions.

  In a sense, FrameMaker treats conditions like processing instructions. If you need to export a document structured in XML and view it with a browser or a text editor, you can find instructions for treatment that punctuate the beaches of conditional text.

  So, once again as Michael, the text says conditional is not breaking your structure. It is superimposed on the structure.

• "Scaling of epizootic ulcerative syndrome and build the waveform (slna)" and "table of string in string delimited a comma."

  I'm taking a picture of waveforms and the units of the scale accordingly.  I have a picture of the sensitivities that the user can change and do this in my "EUs Scaling" under VI.  I would use just of "LAS scale voltage to EU VI LabView", but the sensitivity of my sensors will vary depending on the way through.  I can't much the back wave of construction. I think I'm scaling of values of y in my sub VI correctly.  The sub VI is inside a loop of acquisition data and after reading MX DAQ.  The sub VI is "Scaling had 32ch".

  In addition, when you use DAQ MX create channel he wants to channel names to a string of nouns that are delimited by commas.  How do I take a string array and comma delimit them into one string?

  They are here in 2009.

• Conversion of data in a table by using a For loop

  I'm trying to transpose data in a table using a loop from the size of the array, and then decrease until 0. Can someone help please if you have an example?

  This looks like a school exercise.

  Determine how to calculate the index in the input array and how to calculate the index in the output array. Use the Index and tunnel exit autoindxing table or Index table, and then replace the subset of the table.

• Conversion of integer string String table

  I have two text files, numbers (signal1.txt and signal2.txt). I want to convert it to an array of integers and have a process on them. When I got diverted by control Fract/Exp to string number, it just shows 0 (you can see in the attached file). How can I get the right numbers?

  Please, look at the new code and let me know your ideas. Thank you in advance.

  • You don't need the average shift register, simply use a conditional tunnel.
  • You don't need to chop the upper and lower bays. Work in place and keep track of the current index.
  • The latency control belongs before the loop, so it can be folded for the duration of the loop. I don't know that it will be (and should!) not changed between two iterations, right.
  • Most of your logic Boolean are balderdash is meaningless. For example "= 0 > 0 AND" will be always wrong!
  • Why are there at - it a delay 2 s in the loop? Just for debugging?
  • Are you sure of the wireline number n is correct? I think you have run out of elements well before that.

• Table 1 D (Double) in a menu drop-down

  Hello together,

  I would like a transfer of table 1 d to a drop-down.  Is it possible?

  Greetings

  Peter

  LV2011

  You must use the [] strings or property [] strings and values in the drop-down list, depending on what you want the value of the drop-down list to return. The part of [] strings returns the text you see when you click on the control and display the drop-down list. The fact Values [] property refers to the value that is returned when a selection is made. Normally, it is an integer value that refers to the index. You can return a different value if you wish, but you must explicitly set.

  Ownership chains [] is just a 1 d of string array. So, you can simply use string functions to convert your table to an array of strings and that thread then the property [] Strings.

  String [] and [] values property is an array of clusters. You would have to combine a string (the text) and the value in a cluster and then set up a table. Indexing for auto-loop is the easiest way to do this.

  If you do not undestand what an autoindexed of the loop is, or what group is, then you need to spend time in the LabVIEW tutorials. To learn more about LabVIEW, it is recommended that you go through the material in the introduction, tutorials and other material in tutorials the NI Developer Zone Learning Center , which provides links to other materials and other. There are also several technical resources. You can also take a course online for free.

• The external table, question of double data type

  Hello

  We are the migration of 11g CL8MSWIN1251 to 12 c UTF8.

  Now, we test the exteranl tables and that we've met the problem below.

  We have a binary file (little endian) with fields of type double.

  In 11g, it is very well analyzed, but in 12 c obtained ' ORA-29913: error in the execution of legend ODCIEXTTABLEFETCH"" "".

  In the Oracle docs, I found this paragraph, the last sentence of worries.

  The DOUBLE clause indicates that the field is the same format that the C language, data type DOUBLE on the platform where the access driver is running. Use of the DATA IS {BIG |} LITTLE ENDIAN clause} can cause data to byte - swap before it is stored. Such data may not be portable between certain platforms.

  Here is an example of a test that works on 11g, Oracle Enterprise linux 6.5. And get the error above 12 c 7.1 OEL

• What is the difference when you call the function table() or through double.

  Hello
  Let's say we have feature like this (from asktom):
  

  CREATE OR REPLACE FUNCTION non_pipe_fnc
      RETURN all_obj_tt IS
          all_obj  all_obj_tt := all_obj_tt();
      BEGIN
          FOR r IN (SELECT * FROM ALL_OBJECTS)
          LOOP
              all_obj.EXTEND;
              all_obj(all_obj.COUNT) := all_obj_type(r.OWNER,r.OBJECT_NAME,r.SUBOBJECT_NAME,r.OBJECT_ID,r.DATA_OBJECT_ID ,r.OBJECT_TYPE,r.CREATED,r.LAST_DDL_TIME);
          END LOOP;
         RETURN all_obj;
     END non_pipe_fnc;
  /

  I can call him as select * from table (non_pipe_fnc);
  or
  Select double non_pipe_fnc;
  
  Is there a difference, performance wise or another?
  Kind regards.
  Greg

  I can call him as select * from table (non_pipe_fnc);

  It returns all the columns in all_obj_tt

  or
  Select double non_pipe_fnc;

  It returns a single column of type all_obj_tt
