Questions about equivalents of audio/video and digital/analog.

[Jerry Avins]

Look at the ISD MicroTAD-16M.

It can store 16 minutes of voice in 3840K memory cells,
and a 4kHz sampling rate.

It claims 100 year retention in the non-volatile memory
cells, with 100,000 record cycles. It sounds like they
use a memory cell similar to flash RAM, but store an analog
voltage in that cell instead of only two states.

So the audio is sampled but not digitized. Interesting! I'm downloading
the data sheet now.

Digital circles??? Now we're really going off the deep end.

A hit already! Ah the power of words. Metaphors-r-us. Clearly I should
have said "digital people going round in analogue circles". When
~everyone~ has lost all sense of perspective, the sense of humour is the
first casualty.

How about a "quantized circle" then - an octagon?

Digital is a series of square waves. I know because I can see them on
my 'scope. Think of TTL.

Oh gosh, one of the standard waveforms on an analogue synth is the
square wave. I think people were doing that before TTL was actually
invented. Moog had PCM (meaning, variable duty-cycle) square waves
coming out of his VCO in 1966, if not earlier. What about a sawtooth
wave? That's a series of straight lines too.

It is a well-known and well-documented fact that a digitally sampled
circle, regardless of the sampling rate, *cannot* be converted back
into a perfect analog circle. The mathematical proof of this was
presented at a meeting of the Royal Society in 1681. Look it up.

Interesting! In 1681 too! The first use of the word "digital" not
connoting fingers. Exactly how does one sample a circle with ones fingers?

This is fun!

Hmmmm...so could a person with no fingers still be
considered a "digital person"?

Oh Richard! I saw it as an excellent spoof. As you wrote, "the sense of
humour [sic] is the first casualty. Speak for yourself!

Toes, my friend, toes. OT. Words to a Mozart horn concerto:

Moses suppose his toeses are roses
But Moses supposes erroneously ...

Cool. Or: delivering it through a letter-box one piece at a time. The
question is then - how does the receiver know they have got the whole pi?

Oh - you're thinking of the guy who developed the innovative feature
in the Apple Macintosh windowing system... a little mini-window which
would pop up, *mostly* block what was behind it, but let you move it
out of the way if you really needed to. "Quasi-modal" dialog boxes...
quite a coup for Apple, back in the Day.

I understand that something similar has just shown up in Vista.

They will never know, because Pi is endless.

I think might have been his brother, Quasi-analog.

I was thinking about this yesterday. In the easy cases digital
signals can be NRZ coded. (That is, some voltage for a zero,
a different voltage for a one.) The logic can be implemented
simply with transistors that are either off or on.

As distances get longer or frequencies get higher, analog
techniques are needed in processing signals. Modulation methods
are used to make it easier to separate out the signal from
the noise, and to recover the clock that would otherwise be lost.
At that point, it gets confusing whether the signal is "digital"
or "analog."

Being able to travel faster than the speed of light would lead to a wide
variety of bizarre consequences."

Your reliance on the "theoretically impossible" would have stopped such
research before it started. You might even be the last person around
that believes in phlogiston. Hard to tell.

Oh, I definitely believe in phlogiston - you can see tons of it on USENET
any day of the week! ;-)

To communicate faster than light, you have to interface with the Aether,
which most people don't even believe exists! =:-O

Cheers!

Ah but they do! Now called the Higgs field; soon to be evidenced by the
LHC, when they finally detect the God Particle. Until then it is just a
particle of faith.

It is? Then how come they always are out of Pi
when I want more?

Must be. People keep telling me pi are square, but
all I see are the round ones...

Yes. Pi are round, cake are square. ;-)

Actually, you don't need faith any more, according to God's website:
