    Can anyone point me to a URL for an original on this?

    There are several references to it, but no quotes.

    What I'm particularly looking for is the original justification
    for the claim that sampling is the mathematical equivalent of
    multiplying by a comb of Dirac's Delta Function and its delayed

    This claim does not appear in Oppenheim & Schafer which is
    referenced as the "bible" for DSP, and yet appears in all
    modern texts.

    The claim is at odds with everything that electrical engineers
    are taught about Delta Functions up to that point.

    I'm sure that Brian could explain this to you if you asked him nicely.

    Then again you wouldn't understand it.

    I'll pop over to and ask him for you.

    That rather depends on what they were taught.

    It doesn't contradict anything we teach or that I was taught.

    I suggest you go off and think about it.

    Be warned that this thread is likely to degenerate very rapidly into
    contributors be told to 'Grow Up!' and that they are a 'Silly Girl'.

    OTOH you may know that already......

    Why not come and join the fun in Airy posts his crap there
    quite a lot. You can explain things to him there.

    Sure thing. Airy will threaten your family if you upset him.
