How to get frequency at Max amplitude

I m acquiring a waveform from the DAC which as a maximum amplitude at a some frequency. I want to use that frequency at which the max amplitude is seen for further processing. Now how can I detect the frequency at maximum amplitude ?

Hi micro,
your post is not fully clear to me...
It seems you need some FFT operation to get the max frequency peak.
Otherwise it makes no sense to ask for a frequency at a certain amplitude peak...

How to get the last (max of string) row with multiple records for same ID

Hi all,
I have a query that returns for each client ID the telephone nr, mobile phone nr, email etc...
There is also a column FLG_DEFAULT that indicates if the phone is the default one or not (N= changed).
Basically what I would like my query to return is the phone number where FLG_DEFAULT = N, if this number is NULL or if FLG_DEFAULT =N does not exist I want to return the phone nr from DEFAULT_FLG = Y.
Anyone know how I can do this in SQL? I cannot get a maximum because the format is string (e.g. +32/xxx xx xx or xxx/xx xxx xx.
Thanks!

;With cte As
(Select ClientID, PhoneNumber,
Row_Number() Over(Partition By ClientID,
Order By Case When FLG_DEFAULT = 'N' And PhoneNumber Is Not Null Then 1
When DEFAULT_FLG - 'Y' Then 2 End) As rn
From YourTableName)
Select ClientID, PhoneNumber
From cte
Where rn = 1;
Replace column names and table name with your column names and table name.

so basically i would first denormalize the data using the pivot column and then use min and max to get the slot_start and slot_end.
But then i
can get the min and max ... but not the orignal values as well.
Any thoughts would be appreciated.
Thanks

If you want to end up with one row per slot per datasource etc, and you want the min and max slots that have the same value as the current slot, then you probably need to be using analytic functions, like:
with t as
(SELECT 1 datasource,101    INTEGRATIONID, 201111     slotdate, 100    SLOT1, 100        SLOT2,    200    slot3, 100    slot4, 100    slot5, 100    slot6, 300    slot7, 300    slot8, 300    slot9, 300 slot10 FROM DUAL union all
SELECT 1,    101,    2011112,    200,    200,    200,    200,    100,    100,    100,    100,    200,    300 FROM DUAL),

How to get sum from max value

Hi Experts
I stuck with small problem ,any one please solve the problem i appreciate ur help
Below is my table , i need to get maximum operation i..e from order 10 the maxi operation is #/02 and for order 20 operation is #/01 . and i need to sum it up for respective operations Actual qty values ..
Ext material grp Order Number   Operation key    Actual Qty
100 A.H               10                 #/01             200
100A.H                10                  #/02            300
100 A.H               20                 #/o1             100
100 A.H               30                 #/02             400
i want to show the table like
                       Operation Keys
Ext material grp        10         20
100A.H                  100        700(300+400 )
All Objects from same dataprovider,
Please help me on this .

Hello,
I am having some difficulty interpreting your requirement. You say:
I need to get maximum operation i..e from order 10 the maxi operation is #/02 and for order 20 operation is #/01
Is the output you described more likely to look like that below?
Ext material grp..... Order Number.....Operation key.....Actual Qty
100 A.H.........................10....................... #/02.............. 500 (200 + 300)
100 A.H........................ 20....................... #/01...............100
100 A.H........................ 30....................... #/02...............400
If so, you could use extended syntax to pull back the max operation key and actual qty sum in the context of each ext material grp, order number combination (or whatever dimensions are needed to give you the grain needed). EG
max operation key = max (operation key) in (ext material grp; order number)
sum actual qty = sum(actual qty) in (ext material grp; order number)
Hope this helps

How to get SQLite DB to go to beginning of DB on hit MAX ID

Hi,
I'm making a small mobile app that uses an SQlite database. The idea is that the user clicks the 'next record' button and the next record (by incrementing the id 1) is brought up on the screen. However, when the user reaches the last record and clicks 'next' right now, there is a run-time error saying that the record cannot be found (makes sense).
What I can't figure out for the life of me is how to get the database to go back to the first record when the max_id is currently displayed. Any advice would be wonderful. Thanks alot!
Here is what I'm currently trying which doesn't work:
private function nextMoveLPart(event:EffectEvent):void
                    var cardNumber:int = parseInt(cardNumberLabel.text);
                    stmtB.sqlConnection = connB;
                    connB.open(File.applicationStorageDirectory.resolvePath("FlashCards.db"));
                    stmt.text = "IF(id != MAX(id)) BEGIN SELECT * FROM cardItems WHERE id = ?" + " END ELSE BEGIN SELECT MIN(id) FROM cardItems END";
                                stmtB.parameters[0] = cardNumber-1;
                    stmtB.addEventListener(SQLEvent.RESULT, resultHandlerPrev);
                    stmtB.execute();
                    connB.close();

You can add a transient attribute to the Entity object to hold the old value of the desired attribute, then you can add this attribute to the view object.

How to get audio frequency

hello
This is sudhakar
working as a programmer on Java
now we are implementing audio recording and playing..
but here we are facing one problem..
that is .
how to get the audio frequency...that is pitch but
it variate the pitch which during the play...
if any sample code please send them..
j.sudhakar

If you want to implement an amplifier like most Players have,
that's not that easy. You will have to look for "Discrete Fourier Analysis" I think. You will have to deal with imaginary values (that is the square root of -1), if you want to write the functions up from the scratch.
Perhaps there are some prewritten function, you can use.
Good luck

Hi Hari3109,
According to your description, you want to get the max date for the employees, right?
In your scenario, do you want to get the max date for all the employees or for each employee? In MDX, we have the Max function to achieve your requirement. You can refer to Naveen's link or the link below to see the details.
http://www.sqldbpros.com/2013/08/get-the-max-date-from-a-cube-using-mdx/
If this is not what you want, please provide us more information about the structure of you cube, so that we can make further analysis.

How to dynamically adjust Frequency, Phase and Amplitude for a Generated Sine Wave in C/C++?

Hi,
I wonder if anybody know how to dynamically adjust Frequency, Phase and Amplitude for a Generated Sine Wave in C/C++? This is a part of my project: I need to dynamically generate a sine wave voltage signal by some calculation using the data from a simultaneous analog input and another signal.
Your help will be appreciated so much!
Marlon

Hello Marlon,
Here is an example of changing frequency and ampliude for an E-series device in Labwindows/CVI. The programming should be similar in C for your S-Series device. As is says on the linked webpage above, this process is going to be very processor intensive since you will continually be creating a buffer.

If you have labview 8.x or 9.x you can do this. Go to help in the toolbar. Select "Find Examples" and then search for sound. Locate the "Sound File to Sound Output.vi" This example will help in your task. Remember that Labview is shipped with a lot of useful examples. That can help you in your learning process
Good luck
Ps you can also read wav files, and find examples in Labview 7.x. But I do not know the name of the similar examples in 7.x
Edit: Please use zip files then you are not able to attach files. Do not link to sites outside. The site you linked to was very annoying. Could not download

Besides which, my opinion is that Express VIs Carthage must be destroyed deleted

How to get max and min of a varchar2

there is a column clothes_size in table_1 where i need to get the max and min..how can i get the actual max and min if its datatype is varchar2(50) and not number..how can i do this so that once i have 2 or more clothes_size values returned i will only get the smallest or the largest. i assigned number values on each field and whats next??? any suggestion?
clothes_size
XS                1
S                2
M                3
L                4
XL                5
XXL                6

Examples of this approach:
select min(cloth_size_2) min_size
     , max(cloth_size_2) max_size
from (select case when cloth_size = 'XS' then 1
                    when cloth_size = 'S' then 2
                    when cloth_size = 'M' then 3
                    when cloth_size = 'L' then 4
                    when cloth_size = 'XL' then 5
                    when cloth_size = 'XXL' then 6
               end as cloth_size_2
          from your_table);
<br>
select min(cloth_size_2) min_size
     , max(cloth_size_2) max_size
from (select decode(cloth_size
                     , 'XS', 1
                     , 'S', 2
                     , 'M', 3
                     , 'L', 4
                     , 'XL', 5
                     , 'XXL', 6) cloth_size_2
          from your_table);

How to get the max total sale by date on every store

I am trying to write a query in Oracle which will return both the store_id and the maximum total sale by date

Hi,
Whenever you have a question, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
Explain, using specific examples, how you get those results from that data.
Always say what version of Oracle you're using (e.g. 11.2.0.2.0).
See the forum FAQ: https://forums.oracle.com/message/9362002#9362002

Do you mean you want to see the store_id that had the maximum total sale?
In general, this can be done with a Top-N Query, using an analytic function such as RANK. For an example, see http://forums.oracle.com/forums/thread.jspa?messageID=3739610
If you only want the date, the maximum total from that date, and 1 column from the same row with the maximum (e.g. store_id), then you might be able to use the aggregate LAST function instead.
What results do you want in case of a tie? (That is, if 2 or mote store_ids have the same total sale on a given date, and no other store_id has a higher total.)

How to get this wave profile

How to get the wave profile of the attached vi.
The waveform is made of oscillition of AC waveform. Only the wave profile is useful.
May I know how to get it out.

If I understand you correctly, you want the enveloping curve of the signal or the amplitudes of each period?
Some ideas, you posted too little info on the signal:
* chop the signal with a trigger close to zero, then just take the max for each chunk
* Filter out the carrier signal, use a bandstop filter of the frequency
* Do an AM demodulation by multiplying the signal with a square or sine wave of the amplitude and phase of the carrier signal, afterwards do some lowpass filtering (40 Hz).
