How do you plan the frequency of a Boolean signal?

Hi, I'm new to LabVIEW, so I suspect that it is propbably quite a simple problem.

I'm developing an optical tacometer to a model of gas turbine engine. I have a Boolean signal in labview which is move to a frequency between 4 and 26 Hz. I do need a live display of the frequency of this signal.

Does anyone know how I could do this? Any help would be really appreciated!

Thank you very much

This vi should work for you

    Hi all

    How can I extract the frequency of the FFT function in labview?  Thanks in advance

    Concerning

    If you have the f0 and df, you can find your frequency as you would find the time with a waveform based on t0 and dt.  You just need the index of the data point in that you want to get the frequency.  The frequency is then f0 + x * FD, where x is the index of the data point you are interested in.

  • How do you manage the global permissions?

    As a global organization our counterparts around the world ask access features in Eloqua.  What worries me, is their willingness to create landing pages and emails with no programming experience.  We offer flexibility to our partners, but we find that we have often to recreate what they have planned.  In the end, it's more work on our end.  How do you encourage the use of the tool, while at the same time discouraging programming assets?

    OK - So - here is an interesting idea, at least for emails (not not landing pages).

    And if you allow them to create their own emails, but makes them do to engage? So, you create and manage models... who now may have locked for editing components. (Regular e-mail in E10 generator cannot do yet to my knowledge). They can just update their copy. You can pull the code from the source to deliver, implement E10 email to send then it will hopefully not be all jacked.

    Or, if you're willing to give them more flexibility, you can give them a template gallery and beg and plead and say, then they will be in trouble with [executive name with influence here] if they do something outside of the model. Unfortunately you cannot help but change the model however they want it immediately, but if you give them changes pretty much - different models and configurations for different types of campaigns - in most cases they should be able to find something that works, right?

    I'm sure you have already thought about this... it is a difficult question. You can implement all of the desired governance, but people get to change their habits which is the hard part, especially if you don't have the appropriate level of support to help you grow.

  • In windows 8 How do you do the column bookmarks 'flexible '? I used to be able to make it narrower.

    Windows 8 How do you do the column bookmarks 'flexible '?

    Sounds that you use the bookmarks Menu button that opens a drop-down list.

    Firefox has two buttons bookmark with a star in the window customize.

    A single star button has a drop-marker that opens the bookmarks menu and may appear on the Navigation toolbar or on the bookmarks toolbar if the menu bar is hidden.

    The other Star without the drop-marker button opens the bookmarks in the sidebar (view > sidebar > bookmarks).

    Hello

    When you use the application of the training session, choose the type of activity that best fits your business. For anything else - like weight - select the other category.

    During the follow-up of one year to the next helps:

    • Activity app will credit the ring of progress of exercise with one minute for every minute of the workout.
    • Active calories will be based on the data recorded by the heart rate sensor or a brisk walk, whichever is greater.

    Note, however, that the heart rate sensor is likely to give better results for the workouts that involve rhythmic (for example running) rather than the irregular movements.
