How to initialize the State of the filter?

Hello

In a VI I have continually acquire and filter several different signals (with for example the Butterworth filter or the Butterworth filter point by point). The problem is that whenever I call the filter vi ti eithers begins from a State 0 or state that he had when parsing the previous signal (depending on the Boolean control).

What I need to do is to read the final State of the filter when it finishes a piece of 'signal' A filtering. Then, the next time I need to filter a piece of the signal, I could feed these values as the initial state to the filter.

In fact, I opened the VI of Butterworth filter, then inside, I opened the cascade IIR filter inside, and there is shift registers giving access to initial and final of the filter States. But since it's in the Labview libraries, I can't edit them.

I have also noticed that if I in independent bodies VI of VI for each signal, then each keeps track of its own States. But I have more than 25 different signals (and the number changes all the time) so it's not a viable solution.

Was the answer, but post here in case someone else has a similar question.

VI's like filter Cascade IIR with I.C. (initial condition instead of the initial state, that is why I did not before), allow you to initialize the filter and save its State for later. The only thing is you need to do your own coefficients with something like Butterworth Coefficients VI or more. But it is also an advantage, since you do not need to use each iteration time recalculate the.

  • How to lock the filter radiation bevel/gradient? or other alternatives?

    Hello

    I'm using the filter bevel to add some kind of radiation gradient 1 to my symbol, but when I turn the symbol of changes in bevel if I flip it. How keep/lock the filter bevel at the same place no matter how I rotate? If this isn't the case, are the other alternatives?
    I also tried radiation gradient tool, but it will not change now when I turn it

    you will need to use actionscript to do.  because the bevel "angle" property, you will need to reassign as the object rotates.

  • How to apply the filter to a specific column condition, but not to the report?

    Hello

    I'm having a problem in the application of a filter to one of the column condition.
    I have a scheme with the table around 10 dimension tables and a fact. My requirement is to provide a count on the table of facts with associated with some other columns in the dimension tables.

    Lets consider a scenario with tables as sales (Fact), region (Dimension), Year (Dimension), Type of sale (Dimension).

    Now my requirement is to highlight the fields

    City (Region) - city
    Year-
    Sales Count (dirty table) - number of all sales of the fact table
    Sales Count (dirty table) - count of all sales of the fact which type of sale table is 'Cash'

    Here, my question is how to apply the filter condition of Sales Type = 'MONEY in' only on one of the Sales Count column that comes from the fact table. I want to be ordered for the fourth column, the filter condition.

    Can someone let me know how?

    Thank you

    You must do this:

    1) click the button column fx sales. (This procedure does than on fact, not attributes.0

    2) click on the filter button.

    (3) select the size of sales from the left Type "selection list."

    (4) in the filter window, enter CASH, and click OK.

    This will create one filter on sales 'use' size 'type sales' as the filter. It willl filter only to this column.

    How do I initialize it?

    Usually, you can initialize the disk by DiskManagement.

    In disk management, right-click the disk you want to initialize and then click on initialize disk.
    In the dialog box initialize the disk, select the disk to initialize.
    You can choose to use the master boot record (MBR) or the style of partition GUID partition table (GPT).

    Once a disk is initialized, you can create partitions on it.
    After you create a partition, you can format the partition to create a filesystem (NTFS).

  • How to change the filter to the filter by another column - group calendar page 1

    Any version of the Summit either 4.2 or 5.0 - windows 7 OS

    I know it's a very simple question, but I can't understand this.

    I want to change the filter on the group calendar page 1 of the default "Event status" below

    filter1.PNG

    The only code that I find is shown below.

    filter2.PNG

    I added my own selection list of the button with the following code bar

    < tt > Select GroupName, group_id from EBA_CA_EMAIL_GROUPS ORDER BY GroupName < /tt >

    But when I change the selection list from one option to the other that the calendar is not sorted by events that have particular GroupName. I tried to replace the code in the default selection list and it did not work. There must be another code, check the filter.

    How can I add my own list of selection and filter calendar events based on that select list option is selected?

    Probably you meant 'filtered' rather than 'sort '?

    I tried to replace the code in the default selection list and it did not work. There must be another code, check the filter.

    In the Group APEX 5.0 calendar application, the filter is implemented in line 20 of the schedule area source query:

    select e.event_id,
          case when et.display_color is not null then
                'apex-cal-'||
                (select lower(cp.color_name) from eba_ca_color_prefs cp where cp.bg_color = et.display_color)
          end css_class,
          e.event_name,
          case when e.display_time = 'N'
                then trunc(e.event_date_time)
                else e.event_date_time
                end event_date_time,
          to_char(e.event_date_time,v('APP_TIME_FORMAT')) disp_time,
          substr (
          case when to_char(e.event_date_time,'MI') = '00' then
                ltrim(to_char(e.event_date_time,'HHam'),'0')
            else
                ltrim(to_char(e.event_date_time,'HH:MIam'),'0')
            end|| ' '||e.event_name,1,255) disp_col
      from EBA_ca_events e,
          EBA_ca_event_types et
    where (:P1_EVENT_TYPE = e.type_id or :P1_EVENT_TYPE is null)
      and e.type_id = et.type_id (+)
    

    with P1_EVENT_TYPE being included in the property of the region and by using the action Elements of the Page to send dynamic update schedule to trigger a refresh of partial page in the calendar area.

    How can I add my own list of selection and filter calendar events based on that select list option is selected?

    1 create your filter as a copy the item P1_EVENT_TYPE item.

    2. replace the LOV definition by the code you need.

    3. Add the necessary filter predicate in the WHERE clause of the query source region.

    4. Add the name of your filter element to the region of the Items property of the Page to send.

    5. Add the name of your item to the Items property in the when section of action Dynamics to update the calendar .

    I made a few changes in your application, added a transitional and populated with lov accessor and applied the filter on departmentid of this transitional

    Check it out, in the same way, that you can do for other attributes

    In fact I think that it is the default when you apply lov on certain attribute and then filter works in this way, or you enter the string full or just the value of the id

    Hi all

    I could solve the problem.

    Clear the fault and implicit criteria VO display!

    Here's the code to do the same.

    Hope it will be useful for others as well, also let me know if this can be done in the best way.

    Bean code:

    DCBindingContainer links =

    (DCBindingContainer) BindingContext.getCurrent () .getCurrentBindingsEntry ();

    DCIteratorBinding data binding =.

    bindings.findIteratorBinding ("TestDataView1Iterator");

    If (dataBinding! = null) {}

    ViewObjectImpl = testDataVO

    (ViewObjectImpl) dataBinding.getViewObject ();

    testDataVO.reset ();

    The below two lines code clears the default and display implicit criteris

    which gets set in ViewCriteriaManager when we filter the data in the table to help

    This table filter text box in the column af:table headings

    NOTE: It will not erase the other criteria of which are defined by users in VO

    testDataVO.getViewCriteriaManager () .removeViewCriteria (ViewCriteriaManager.DFLT_VIEW_CRITERIA_NAME);

    testDataVO.getViewCriteriaManager () .removeViewCriteria (ViewCriteriaManager.IMPLICIT_VIEW_CRITERIA_NAME);

    If (param.equalsIgnoreCase ("home")) {}

    testDataVO.setWhereClause ("attachment = 'Y'");

    } else {}

    testDataVO.setWhereClause ("attachment = ' n '");

    }

    testDataVO.executeQuery ();

    }

    Thank you all for the suggestions.

    Thank you

    In the source of the interface panel, drag a column from the data store (already on the plate) on the gray background of the source Panel. This opens a filter window, you just fill.

    If you've added filters to the source table in the data model, if you drag on the Panel of the source of an interface, filters come with her. You can then adjust/multi-override as required.
