Bad results value amplitude and phase
I try to add two Phasers of tension and to get incorrect when simulated results on Multisim using the frequency unique AC analysis. I changed the amplitudes of analysis AC from both sources to their respective values of 20 and 15 volts. The result of the addition should be size = 25 volts peak and phase = 66.87 degrees, which does not match results of Multisim. What I am doing wrong?
Thank you in advance.
You must click twice on the fickle source V1 and V2 and the "AC size' and the 'magnitude of AC Phase', change the settings.
Also, depending on your preference, select Options of Simulation global preference, time = 0 if you want the right to shift to change phase or left, you can configure it here. This setting affects your calculation of phase.

Hi, does anyone know how to find the RMS or amplitude and phase to the fundamental frequency of a signal measured in Labview?
I tried with the Analyzer for harmonics of buit - in, but he can't give the values of the phase angle. I also tried the FFT VI spectrum, but I don't think the results are good.
Harmonic distortion Analyzer is a polymorphic VI, this means that if you connect a single signal in and then you get a unique signal, and if you connect a table of signals in out you a table.
The VI I is not polymorphic, but you can easily change to work with multiple signals. If you look at the standard implementation for the harmonic distortion Analyzer N-channel then, he simply called the channel 1 harmonic distortion Analyzer a loop for. So you can easily call my VI in the same way. See attached screenshot:

See attached vi. Very well, the chart, I see that the dominant amplitude is 3 with dominant frequency of 100 Hz. But how to do that 3 and 100 of the value from the waveform data in a variable double?
I think I have the output waveform for measurement of the Spectra vi table and then do some math on it maybe high percentile or something, but that is awkward! Is there a special feature that can quickly the value of amplitude and dominant frequency?
O! blind me! Use max array and index. Solved already!
Could any such a me when we encounter this bug? Please help me with a simple example so that I can search for them in my PB.
Bug / / Desc: BAD RESULTS WITH OUTER JOINS AND TABLES WITH a CHECK CONSTRAINT
I ran the outer joins with check queries constraint 11G 188.8.131.52.0 and 10 g 2, but the result is the same. Need to know the scenario where I will face this bug of your experts and people who have already experienced this bug.
SQL> select * from v$version; BANNER -------------------------------------------------------------------------------- Oracle Database 11g Enterprise Edition Release 184.108.40.206.0 - 64bit Production PL/SQL Release 220.127.116.11.0 - Production CORE 18.104.22.168.0 Production TNS for Solaris: Version 22.214.171.124.0 - Production NLSRTL Version 126.96.36.199.0 - Production
Why do you not use the description of the bug test case in Metalink (we obviously can't post it here because it would violate the copyright of Metalink)? Your test case is not a candidate for the elimination of the join, so he did not have the bug.
Have you really read the description of the bug in Metalink rather than just looking at the title of the bug? The bug itself is quite clear that a query plan that involves the elimination of the join is a necessary condition. The title of bug nothing will never tell the whole story.
If you try to work through a few tens of thousands of bugs in 188.8.131.52, of which many are not published, trying to determine whether your application would be affected by the bug? Wouldn't be order of magnitude easier to upgrade the application to 184.108.40.206 in a test environment and test the application to see what, if anything, breaks? Understand that the vast majority of the problems that people experience during an upgrade are not the result of bugs - they are the result of changes in behaviour documented as changes in query plans. And among those who encounter bugs, a relatively large fraction of the new variety. Even if you have completed the Herculean task of verifying each bug on your code base, which would not significantly easier upgrade. In addition, at the time wherever you actually performed this analysis, Oracle reportedly released 3 or 4 new versions.
And at this stage would be unwise to consider an upgrade to 11.2?
After inputing the values in a table, and make a scatterplot graph-, I click on 'series' adds a linear trendline and check the boxes for 'show R²' and 'equation '. The two appear on my chart, but they always seem to be rounded. My equation is always "y = x" and my ratio is always 1. Even if my partner will get the same results in Excel and get an equation like ' y = 0.9888 x + 0.00044. Is there a way to fix this? I'm doing something wrong?
Here is an example I did. Perhaps you could share your screenshot of dan for the chart:
Face because of function result value user was too big while I extracted and insert the XML into an oracle table. That is, it works fine when the XML size less than 4000 characters, but the issue will increase when the xml code size more than 4000 characters.
I can't able to unravel using gently question out of the question.
Thanks and greetings
This is my code:- INSERT INTO ENDORSEMETN (Endorsement_name) SELECT EXTRACTVALUE (COLUMN_VALUE, '//Table1/Endorsement') FROM TABLE (XMLSEQUENCE (EXTRACT (SYS.XMLTYPE (p_xmlDetails),'/NewDataSet/Table1')));
Although the syntax is supported from 10.2.0.4 (ou.3), the ability to directly throw text() big bows that CLOB has been added in version 220.127.116.11.
SELECT endorsement_name FROM XMLTable('/NewDataSet/Table1' passing xmltype(p_xml_Endorsement) columns endorsement_name clob path 'Endorsement' ) ;
On older versions, you can use this trick:
SELECT dbms_xmlgen.convert( xmlserialize(content endorsement) , 1 ) as endorsement_name FROM XMLTable('/NewDataSet/Table1' passing xmltype(p_xml_Endorsement) columns endorsement xmltype path 'Endorsement/text()' ) ;
< psoID ID = "user id" / >
How to get the value of the ID as the user id. And how to put the run value on it?
I can think about is that
/psoID/@ID/value GOLD psoID/@ID/*[local-name () = 'value']
And how to put the value inside ID ="? »
Because we are dealing with a structure of type anyType you must use the functions of node (local name) in combination with predicates () to read or write values (node) of the element:
To read the value for example use the copy rule:
This wil read:
on the message:
You will see the value 'B '.
To write, you use:
When you enter a query like
SELECT count (*) FROM my_table t WHERE contains (t.co_xml,'hasPath(/tag1/tag2)') > 0
I get bad results if tag2 is an empty element tag (< tag2 / >) that appears somewhere in the
XML instance, but is NOT directly under tag1.
For example, the following XML instance is (but shouldn't!):
< a >
blah blah < tag3 > < tag1 > < / tag3 > < / tag1 >
blah < tag4 > < tag2 / > < / tag4 >
< /a >
This seems to happen only for the empty element tags. Is this a known bug and does anyone know of a workaround?
Thank you in advance for your help!
Like you, I've been looking in the wrong places, bug of thought, rather than documented behavior. Finally, I came across the following excerpt from the next section of the documentation on haspath in Oracle text reference.
Because of the way in which XML data section are saved, false match may appear with XML sections that are completely empty as follows:
A query of HASPATH(A/B/E) or HASPATH(A/D/C) falsely corresponds to this document. This type of fake correspondent can be avoided by inserting some text between the empty tags.
We will store the objects in a distributed cache (version 3.3) using objects versionnables for optimistic locking. Objects stored in the cache are anti-theft with POF. However, it seems that for values () .contains () and containsValue(), equals() is never called on these objects. The problem we have is that to implement versionnables, we use a field long version, but I deliberately don't compare this field in equals(). However, this means that if I have an object, insert it into the cache and immediately call containsValue() return false(). As far as I know use of the debugger, it seems calling equals() directly on the binary object stored in the cache, which is almost never what you want.
Y at - it a good solution for this?
See you soon,.
I would like to raise objection: that's almost ALWAYS what you want because otherwise, data must be deserialized each time put or get important takes place resulting in a drop in performance!
From my experience, it's ok to compare the form serialized about 99.5% of the time. In the rare cases were you really want to do something special in the equals method, it is of course a royal pain in the XXX that it is made this way...
Otherwise, you're right - this is how it works!
Had to rebuild my Satelite A40 from the recovery CD and I get a message asking me to install a TOSHIBA ACPI-Based added value logical and objective general Device Driver. He can not find a file called tvalz.sys and I can't find a download appropriate on this site... can someone advise. Thank you James
Hmmm I think that ACPI-Based added value logical and objective general Device Driver belongs to the Toshiba common Modules.
This utility of common Modules can be found on the European driver Toshiba page.
Download and just install it again.
But I wonder why you should install it after using the Toshiba Recovery CD? :|
The restore CD contains all the necessary drivers, so I think that this common modules must be installed. But who knows
Try my advice and install the common Modules as shown above
I used 2 USRP in reception. They are connected together via a cable Mimo.
I want to locate the source of the issuer. So I need to synchronize the two receivers.
I did the constellation to the two USRP:
1 - with identical cables 2 - with different cables.

I have synced my receivers (in time and phase)?
Please help me
I'm working on a proper VI for my building project, but there is a problem... The project here is to define the occurrence of the error and the error type to decide what actions are required to protect the circuit. This isn't a problem here...
The problem is when I run the VI for the first time... Everything is good and I got what I need... But when I run it after that... The new results to come out with the results of the first round... So my problem is with the previous results of LEDs and indicators of compensation
Hope my question is clear and not confusing
Well, show us a code instead. How do you call the VI?
Have you tried the option: "properties of the VI... run... clear the flags when called?
How to find the value max and min for each column in a table 2d?
For example, in the table max/min for the first three columns would be 45/23, 14/10, 80/67.
With color on your bars, you should have enough experience to understand this.
You're a loop in the table already. Now you just need a function like table Max and min. loop. And you may need to transpose the table 2D.
I am trying to simulate the loop gain and phase for an oscillator in multisim. I use the Middlebrook method and can get the gain in current and the gain in voltage by using the function "add the words" in the analysis. Then, I need to use these winnings to calculate the loop gain and phase using the equation T = ((Ti*Tv)-1) /(Ti+Tv+2), where Ti and Tv are respectively the current and voltage gains. I have been unable to bring the last expression and will appreciate any help.
Yes, the Middlebrook analysis technique can be implemented with Multisim. Please see the circuit below as an example on how to apply this method in Multisim.
Let me know if you have any questions.

My windows Defender is set to off, when I try to change as a result, he stops and tells me to reset, I try and it always goes back to zero.
How can I solve this problem
1. what operating system is installed on the computer?
2. were there any changes (hardware or software) to the computer before the show?
3. What is the full error you get, when you try to activate windows Defender?
4. what anti-virus is installed on the computer?
Method 1: Check if the Windows Defender service is enabled.
a: Type Services.msc in the start search box and click on enter.
b : now, look for a service called Windows Defender, double-click to open it.
c: Now Start the service and make sure that it is set to automatic.
Method 2: Temporarily disable the antivirus and check if the problem occurs.
Note: Activate the anti-virus program after you perform this step, because it would protect your computer from threats.Note: If there is an antivirus installed, then it might be turn off Windows Defender, so temporarily disable the antivirus and check if the problem occurs.
Hope this information helps.
