    Can anyone define these abbreviations for me?

    ATM in video transmission
    EPR in radio

    ATM is Asynchronous Transfer Mode. It uses a different structure for its
    packet sizes and service levels. ATM isn't just for video and it is one of
    the technologies that saved the Internet. If you look at some diagrams of
    the Internet you can usually see the infamous ATM cloud where traffic goes
    in then gets shifted around according the ATM protocol. It is capable of
    handling a lot more traffic more efficiently then traditional TCP/IP...
    Internet backbones use ATM...

    Not sure on the other stuff though... :)

    For more info about FFTs, you might want to check my series
    of articles on "Gut-Level Fourier Transforms - Everything You
    Need, You Got In High School" at
    Also a slightly different presentation of the same material at

    Hope this helps!

    Subject: Abbreviations
    You've already got ATM (Asynchronous Transfer Mode) and FFT(Fast Fourier
    Transform) from other posts. EPR in radio means Experimental Packet Radio.
    Google is your friend. Look up these acronyms followed by the words spelled
    out, and enjoy.

    Good luck

    I have to wonder, though, if that was a typo and was
    SUPPOSED to be ERP, for Effective Radiated Power...

  7. And there lies the problem with acronyms. In film to video, EPR is
    Electronic Pin Regisration. Seems every field just has to have a way
    to exclude people by using jargon. You sure that isn't an Automatic
    Teller Machine or maybe an Anti Transistor Moron, you know the guy
    with the toobz?

    Well, we know it's not the box they get cash out of - that's an
    automatic teller machine machine. ;-)

    No it's not, it's a 'cash machine' :)

    It's those bleedin' colonials with their ATMs, VCRs and SUVs that are
    causing all this trouble... ;-)
