Sorry to disagree but to illustrate: I asked a  Polygram  engineer  during  a 
live recording session how it was possible to record to apparently <1dB of 
clip. He shrugged and just replied "It's ok if they play in tune" 8-)

That was a few years ago when the recording was onto 1610. Since then 
recordings at > 16 bit are possible if not common, but your point is valid 
for unpredictable sound sources.

A long time ago we designed a limiter for use before A/D -- it has never sold 
for the purpose.

Sorry.  Fade a signal down to -80dB and listen. Just some added hiss and _no_ 
noticable  distortion.  This  is  what dither is all about.  I have a digital 
fader (re-dithered) which sounds ok when the music sound is at the same level 
as the noise.  Switch the dither off and there is your  distortion  (or  more 
precisely  quantisation noise which sounds a bit like crossover distortion to 
me).

Even if there is distortion, it would have to be very bad to exceed the noise 
floor.
All this does of course assume that the CD DAC is good, but that is not the 
subject of this thread.

Perhaps I should pass you the fader handheld when it's faded also to zero but 
the monitor gain is right up. 
What is 80dBs above 1 watt per channel?

This way works fine, of course.  If you have a lot of holes, though (especially
if they're sizes that you don't have a punch for!), a milling machine is
the standard way to cut rectangular holes.  (The edges of the rectangle have
a radius the same as whatever mill bit you used, of course, so you need to
use a square file afterwards.  But filing is easy on aluminum.)  If you
have access to a reasonably well equipped machine shop, you'll also be able
to cut parts of circle in probably any size you'd like (crescents, circles
with square protrusions, etc.)

Yeah, I've nibbled plenty of holes myself too.  Too bad the cheap nibblers
won't do 1/8" front panels. :-( (Not that you _have_ to use 1/8" panels...
that's just what we use around here.)

I wish I could afford one!  They're about $250, as I recall.  (And even if
I make 50 punches with it in the next 5 years, that's still $5/punch!)

Or, you could capacitively couple the trigger signal.  Saves some gates,

I doubt it.  Look at TouchTone service.  The phone company charges you extra
for it even though it saves the phone company money over pulse dialing.
But who ever claimed the local Board (Bored?) of Public Utilities really
did things in the interest of consumers the majority of the time.

>Should someone that doesn't want their number given out really have to

What about those with unlisted numbers?  NJ Bell charges you to keep your
number unlisted.  If you want someone with Caller ID to _not_ get your 
number, you must also pay to have it blocked--double whammy.

When Caller ID first came to NJ, Ted Koppel interviewed a spokesman for NJ Bell
on Nightline (ABC-TV).  Koppel asked the spokesman about double charging
those with unlisted numbers.  The spokesman should be a politician!  He was
just as smooth at giving a "non-answer".  Koppel pointed out on three tries
that the spokesman had not answered his question.  Finally, Koppel gave up
saying it was obvious that man had no intention of giving an honest answer.

Well, actually, it's the AUTOCORRELATION of a PN sequence that is a large  
positive number at a time shift (tau) of 0.  At non-zero time shifts, the  
autocorrelation is very close to zero.  For maximal length shift register  
sequences (a commonly used method of generating PN sequences), the  
autocorrelation is n at tau=0, where n is the length of the sequence, and -1 at  
any value of tau<>0.  The CROSS-CORRELATION between two PN sequences can have  
large peaks at some values of tau, even if the PN codes are not identical.   
Careful selection of the PN sequences is required in order to have a set with  
good cross-correlation properties.

NNTP-Posting-Host: wellworld

I have an old Lafayette portable tube tester (I think it's model TE-21 but
I don't remember offhand; probably not important) and I'm curious about the
meaning of notation on the tube data paper scroll.

The tester has 10 switches, each of which may be set "up", "down", or
left in the center position.

Per-tube data on the scroll indicates which switches should be set "up" and
which "down".  I assume all the others should be placed in the center
position.

The question is this:  some of the numbers indicated on the scroll for
"up" or "down" for some tubes are printed in bold type (most are
in regular type).  What does bold type indicate?

Replies directly to me, please.  Thanks.

At least you took the time to do a bit of reading about it. It's something 
that isn't made very clear (if at all). 
It's not a read-modify-write instruction and as such is read from the 
pins. ie. you would get the MSB of the last fetch on P2.

Because of that, you can be caught by the pin being externally pulled 
low on any port pin too.

It also makes the MOVX @Ri instructions a waste of time with an external 
code source.

Some months ago, there was a discussion on magnetic levitation here in
sci.electronics. I didn't save any of the postings along that thread, and
since I now find myself _very_ interested in this subject, I'd like to ask
for help. Can anyone send me a summary if any such was ever posted?

Here's what I'd like to do: make a sphere (diameter approx. 25cm or 10 inch)
levitate approximately five cm (2 inch) above a bowl shaped surface.
The coils will (fortunately) be located under the lightweight sphere.

To minimize my own cut-and-try's:
Questions: Where can I find a suitable metal sphere? Would four (or even three)
coils do (for stability)? Have _you_ tried - what's your experiences?


Thanks in advance,
