    I want to know that the extension of the 3-bit binary counter
    so that it can count 9999 digits and display.
    And what ammendments or addition of componenets make it possible ?
    And use the specific digits (at 9 then at 10 then at 20 then at 120 & at 1120
    {Using addition of 10^n ,n=0,1,2,3,4,5 to digit 9 & the to the result obtained by
    this type of addition}
    the output is given to a siren alarm in the form of input to alarm and it will give
    the beep????????

    This is not where you ask technical questions. We also don't use email, we use our forums. Registration is free and easy, but if you are depending on a site like this to save you you should have started sooner.

    Having said all that, there is a homework section. Register and repost there, here the thread is likely to be shut down.

    You should understand that we help with questions and projects, but do not do work to order. It is your assignment/project, and you should be the one doing the designing and building.
