Re:OT: Balanced audio. (Score:0) by Anonymous Coward on Sunday September 23, @10:13AM (#20718849) The difference is the potential, though. (DON'T TRY THIS AT HOME, OR ANYWHERE!:) If you have no load on a standard 120 volt circuit, and stick your finger in the neutral side, you should receive no shock (the neutral should be bonded to ground at the panel). If you stick your finger in the hot side, though, ZZZZap! This is because the hot side actually carries the power, and doesn't return it to ground.
This changes when you put a load on the line, though, as now there is potential available at the neutral conductor. It's still limited, though, as you would become a parallel resistance to ground after a load supplied in series. That means a lot less current to shock you with, but possibly enough to hurt you anyways. However, even under the lightest and heaviest of loads, the hot side always carries enough current to hurt you.
I'm replying to an AC to keep others from being "almost" correctly informed. These remarks pertain to the way things are supposed to be wired in the U.S.
The wire we commonly, though not always correctly, refer to as the "neutral" is the "white" wire. It's sometimes referred to as the "grounded" wire. Don't let that fool you. The green or bare wire is referred to as the "grounding" wire and it is that wire which is only supposed to carry current when something is wrong.
The "neutral" is bonded to "ground" at the service entrance only. If there is a another panel board (one of those gray boxes with circuit breakers) "downstream" of the service entrance, the screw block inside it where all the white wires are bonded together must be insulated from the metal enclosure.
Because conductors have "some" resistance there can be a difference in potential between them.
He's a clever geek, no doubt but he owes everything to the good fortune of meeting Steve Jobs. Without him Woz would still be a calculator engineer at HP.
Are you sure it wasn't the other way around, that Jobs had the good fortune to be in the right place at the right time to exploit Woz's talents?
The way lightning rods work (if properly designed, constructed, and installed) is by bleeding off charge so that it doesn't build up enough to cause lightning. So they're actually good things to have around.
(unlike, say, the 'hot' and 'neutral' in your power socket)
If that's a 120 Volt socket, that's not really a neutral, since it carries the exact same current as the "hot" wire. That's how Ground Fault Circuit Interrupters work, by sensing that the currents in the two wires are not equal, which means that some of it is leaking along another path where it shouldn't be.
You're the reason I have to stand around for fifteen minutes waiting for one of the few employees in the store to open up the glass case where they have to keep everything...
I'm pretty sure the reason for all the glass cases is the people who sneak unpaid for merchandise out the door under their coats without ever involving the cashier or getting a bag with the store's name on it. The guy who gets his buddy to ring up a pack of gum instead of the PS3 he's actually taking isn't being deterred by the glass case.
He identifies himself as 'an "upper middle class 26 year old" ' (that's only a kid to dinosaurs like me) who "In January 2002...started a training and consulting company", and says that he is fortunate enough to be able to afford his legal fees even if they rise to $10,000.
I suspect that the ten grand is pretty much the upper limit of what he can handle without the situation going from some or significant financial pain to financial suicide.
And then, there is the Seagate hard drive that mysteriously will only boot my TiVo about one time out of every twenty (but works flawlessly when attached to a FW/ATA bridge chipset).
And then there's my 80 Gig Western Digital that was very flakey (as soon as the warranty was up) in BX chipset (or equivalent) motherboard PCs, but I used it to replace the original drive in a Series 1 stand alone Philips Tivo and it's been working flawlessly in it for about a year now. Before you blame WD, I'm writing this on a BX chipset PC that's been running another WD 80 Gig that's almost identical (came off the assembly line a few months earlier) and it's been working fine since before I got the newer one that's now in the Tivo. Go figure.
By the way, you aren't the only one running a hard drive cemetary.:-)
Is this the same FBI that has been in the news in the past few years for not being able to get a decent modern computer system in spite of throwing millions of our tax dollars at the problem?
The FCC can re-allocate spectrum which the government still owns, but that which has already been auctioned off they no longer own and those who do own it now would probably tie up the FCC in court for the next hundred years or so (or buy enough congresscritters to land on the FCC like a ton of bricks, whichever is cheaper).
Spectrum that was once set aside for television stations is now desired for other uses, including the important one of public safety, but the government is having to go to a great deal of trouble to get it back from the broadcasters whose only claim to it has been a temporary renewable license to use it (basically at no charge) "in the public interest".
What happens when, in the mysterious future, a new and important use is found for a particular slice of airwaves that have already been sold off? Will it be necessary to go to the Supreme Court to get a ruling that lets the government declare "eminent domain" and force the owner to sell it back? Better to lease it and still get some money out of it but retain ownership and control.
That wasn't a bridge to nowhere, that was a bridge that would have greatly increased the value of land owned by Alaska's other Republican Senator and by her father, Alaska's Republican governor.
TV commercials have been compressed and limited for years now (in pretty much the same way that radio stations did to their whole audio signal on its way to the transmitter back at least as far as the '60s so as to be loudest as you tune across the dial so that you don't miss them--that's why dead air is the greatest sin in radio), so as to be sure to grab your attention and keep you from missing a single word of their vitally important message. The TV stations and networks are stuck with it 'cause it comes to them that way from the ad agency that buys the time.
Your dB meter needle probably won't go any higher during the spots, it'll just go to the peak and stay there.
...as I age I am less and less able to sift background noise from speech.
Try comparing an old movie on Turner Classic Movies with something from the last few years, or an old (late '50s, early '60s) TV show with modern ones, and see if you have as great a problem with the old stuff.
For some reason current movies and television, even PBS stuff, are being mixed and mangled so that the dialogue is getting buried under the background music and sound effects (although part of the problem is probably actors who mumble and can't enunciate worth a damn. It may be more realistic and true to life, but if you can't tell what they said, why bother with a script?).
Our sample then will be 2 bytes long. A byte for pitch and a byte for volume.
I'm thinking that one of us does not understand analog to digital conversion. All along I've been thinking that each sample represented instantaneous amplitude.

Oh, wait, it'd be almost 10 years, I guess.
By 10 you mean just shy of 9, right? 'Cause I got here about this time of year back in '98, around the time of the Halloween Documents.

The networks are paying the advertisers? Where do they get the money with which to do this?
Well, Taco did kill off JWZ about a decade ago. :-)
