How to find the ratio between the two frequencies in the fft

Hi, I'm Jean,

I need to find the ratio of the frequencies of 1st and 2nd graph fft.

Already, I received information of this site only. Mr. Alten helped me.

Now, I have to continue the same problem and need to find the ratio of the frequencies.

Please someone help me guys...

I will attach my vi file and the text file.

John,

Should you report the frequencies or the report of the amplitudes of the components at these frequencies?

The Information.vi of your multiple for the Signal Processing, extract > range of measures of waveform should do what you want.

The frequency resolution is not very good because you have cycles relatively little waveforms (2 ~ for the lower frequency). I added a few zeros to improve resolution, even if a larger sample of data would be better.

  • How to find the point of intersection of the two geometry?

    Hello
    Could someone give some suggestions on how to find the point of intersection of the two geometry?
    I need just point. (x, y, z)
    Thank you

    Can you post the full result of geometry returned?

    What you should have as a result:

    MDSYS. SDO_GEOMETRY (2001, 1, NULL, MDSYS.) SDO_ELEM_INFO_ARRAY (1,1,1), MDSYS. SDO_ORDINATE_ARRAY (2.0,2.0))

    Notice the sdo_intersection will use only the sdo_ordinate_array, even if the result is a point! (with the SDO_POINT is NULL.)

    where do you find these x, y, z values of?

    On your other question:

    -using the operator space sdo_relate (with mask = ANYINTERACT) will return in pairs, the result of the intersection of each anyinteracting polygon, line combination.

    -of course, these results will vary from point, multipoint, line or multiline even depending on how the interaction takes place.

    -try to explain a bit more what do you mean 'I want only points to return' of nit.

  • How to find the name of the Oracle database server?

    People,

    Hello. I installed Oracle Database 11 g 2 OS Oracle Linux 5. The installed directory is/home/user/OracleDB_Home and/home/user/OracleDB_Base.

    Host name is "mylinux". Name of the database instance is PT853.

    I use "mylinux" as the name of the database server, it does not work. I use another way to do as below:

    Export ORACLE_HOME = / home/user/OracleDB_Home

    Can I use "mylinux ORACLE_HOME" as the name of the database server, it does not work either.


    My question is:

    How to find the name of the database server Oracle with Oracle Linux 5 OS?


    Thank you.

    You must learn the basic of database Oracle.

    Please don't regard it not same as SQL server in terms of configuration.

    You never specify the database server name in Oracle.

    You specify the host name in only two places, 1) Tnsnames.ora/JDBC/ODBC (or any client you want to connect) and listener.ora) 2.

    There was nothing called specify the name of the Oracle database from an oracle database server.

  • How to find the last pasted paragraphs FMP?

    I'm sticking FMP several objects at once in a file (a file of changes to the sections containing the changebars) in the main text flow. I want a separator line to go at the end of each pasted section, so I try to insert one after the paste operation. But instead of a line between each section, all lines are added at the end of the file, after all the sections. So if there are 3 glued sections at the end of the file are three lines. My code is below, do you know how I could fix this?

    Thank you, Mark

    function copyPasteChanges (doc, chgRange) {}

    Select the section with changebar and copy it.

    doc. TextSelection = chgRange;

    doc. Copy();

    Prepare for the changes doc and paste there the modified section.

    var firstChgPgf = changesDoc.MainFlowInDoc.FirstTextFrameInFlow.LastPgf;

    var changesTloc = new TextLoc (firstChgPgf, Constants.FV_OBJ_END_OFFSET);

    var changesTRange = new TextRange (changesTloc, changesTloc);

    changesDoc.TextSelection = changesTRange;

    changesDoc.Paste ();

    To go at the end of the file again (I think)

    var lastPgf = changesDoc.MainFlowInDoc.FirstTextFrameInFlow.LastPgf;

    var dividerPgf = changesDoc.NewSeriesPgf (lastPgf);

    var TLoc = new TextLoc (dividerPgf, 0);

    }

    Hi Mark,

    The problem is that the dough does not occur when you think. The dividing line is added at the end of the file, but are not your actions of dough. Actually, I think that maybe a little random where pasta is produced, because this line:

    var changesTloc = new TextLoc (firstChgPgf, Constants.FV_OBJ_END_OFFSET);

    .. .is does not create a valid text location. You can check this by abandoning the service after:

    changesDoc.TextSelection = changesTRange;

    .. and look at where's the insertion point. It will probably be everywhere where you left it last, because the call is not valid. I can't tell you exactly why, except that it has something to do with the fact that you are using the last paragraph in the stream. There is something weird to try to define a range of full-paragraph text with the last paragraph. I'm sure it's related to how the last TFP in a stream does not show a mark of FMP, but beyond that, I don't know how to do what you're trying to do with the last paragraph.

    Having no knowledge of how do it right, any time I need to do this, I create a paragraph "dummy" at the end of the flow to fill that space strange 'last FMP", then do the work around it. In the end, I just want to remove fake TFP. I don't know if it's a good idea or not, but it's the only way I ever get it to work and it sorts the mirror how you could do this manually in the GUI.

    With this, I modified your script as follows, and it seems to work better. Note that I also modified the logic of how to find the last paragraph of the flow by writing a separate function. Your call to the 'FirstTextFrameInFlow' is OK, unless your doc begins to span several pages and/or begins with several empty pages. The function I wrote ensures that you really the last TFP in the stream.

    I hope this helps.

    var changesTRange = new TextRange (changesTloc, changesTloc);

    changesDoc.TextSelection = changesTRange;

  • How to find the size of the semantic model

    Hi all

    Please can you tell me how to find the size of the semantic model.

    Thank you
    INDU

    Hi Indu,

    A couple of several things:

    1 we still need an application, in order to account for the storage of the Table in the Application

    This query gives you the name of application table

    Select the table table_name from mdsys.sem_model$
    where model_name = '';

    This will give you the size in MB

    Select semmodel.table_name, dbaseg.bytes/1024/1024 MB
    of mdsys.sem_model$ semmodel, dba_segments dbaseg
    where semmodel.table_name = dbaseg.segment_name
    and semmodel.model_name = '';

    2. If the model is the only one of the semantic network, you can get the space used by the table of $ RDF_VALUE using this query

    Select bytes/1024/1024 MB dba_segments where nom_segment = '$RDF_VALUE ';

    If there are several models, this space is shared between all of them.

    Kind regards!

  • How to find the employee is rehired

    Hello

    How to find the employee is rehired?

    through Front End and back End

    Thank you.

    You're looking to identify if an employee was re-employed, or looking to find all employees who were rehired?

    To determine if an employee was re-employed:
    (1) place you * HRMS Manager > people > enter & maintain
    (2) look at the employee's most recent Start Date field
    (3) compare this to their first Date field engaged in the Services tab

    If the two are different, it means that the employee was re-employed.

    Technically, each period of employment is linked to their period of Service. They will be on the per_periods_of_service table. So, there are 3 rows in per_periods_of_service if an employee was re-employed twice (that is to say, initially engaged and then reembauche twice).

    I hope this helps.

  • How to find the size of the scheme with or without fragmentation

    Hello Sir,
    How to find the size of the scheme with or without fragmentation?

    to find all of the bytes used by a schema, you can add the bytes for the owner of the dba_segments views.

    for fragmentation, I guess you want to know about the space left between the segments.

    finding depends on the design and standards of your database.

    Each scheme has its own storage space? If Yes, then you can take the total space used in storage and then subtract the number of the dba_segments.
