  1. Re:Why not both? on ITU To Choose Emergency Line For Mobiles: 911, or 112? · · Score: 1

    This is totally incorrect!

    In the UK, dialling a 9 using pulse dialling was very slow.

    New Zealand reversed the numbers on the dial but not the number of pulses so dialling a 1 actually sent the same pulse train as a 9 did in the UK.

    Ahh but you're anonymous and therefore a no-one. I should have said, "anyone who's anyone lusts after a Marshall rather than a Fender" but it seemed a bit pretentiously correct and you know, uncool. But you had to go and ruin it. Your bad.

    So what?

    No one lusts after a Fender amp, they want a Marshall.

    He did it right.

  4. Re:128K should be enough for everyone on Audio Compression Primer · · Score: 1

    Not to put too fine a point on it, this is drivel.

    Your 10kHz waveform sampled at 20kHz can *only* be a sine wave. By definition, if it isn't a sine wave, then it has components at harmonics (multiples) of its frequency which will be outside of your sampled bandwidth. All signals can be decomposed into a set of sine waves and providing all of the frequencies of those sine waves lie within your Nyquist bandwidth, you can perfectly reproduce the original signal, whatever shape it was.

    The reconstruction filter only needs 2 (plus a small delta) samples per cycle to completely reproduce the sine wave, it is in no way an approximation of the original waveform.

  5. Re:Army's stuff on U.S. May Reduce Non-Military GPS Accuracy · · Score: 2, Informative

    Not really.

    You are correct in saying that the diferential station knows where it is to high accuracy. It doesn't act as another GPS station though, it sends out corrections to the received signals from the GPS satellites. Hence it would indeed correct for SA in its coverage area.

  7. Re:There are no analogue networks left in Europe.. on Cell Phones - Analog vs. Digital · · Score: 1

    Simply put, analog towers service fewer simultaneous users, but cover a much larger range. Therefore, if you have lower population density, analog suits you better.

    There is no reason why digital cannot service large cells - analogue is not inherently better in this regard.

    That's probably because his triband phone uses an international standard, whereas the US in it's wisdom decided to have multiple incompatible standards.

    Whilst I agree that Canada is a pretty cool place, if you are serious about your data retention, you would store your CDs in Paris, sitting outside a cafe with an espresso and a pair of dark sunglasses.

    $250k is about right for a 0.25u fab run (and it generally has way more than 4+2 layers).
