It all depends on the crossovers; some (poor) designs can have extremely low reactance at 200kHz+, which can hose amps that are prone to oscillations at such freqencies.
The voice coils are inductors; there is no real way to eliminate all inductance from a traditional loudspeaker. Planar/ribbon transducers and electrostatics are another thing entirely.
Something that runs parallel to this is the world of Neil Stephenson's "The Diamond Age." It goes something like once there exists a secure and anonymous network for individuals to exhange information and transactions, the current world order collapses. Why? Because governments can no longer track the flow of money.
Believe me, I agree with you. I was just trying to show that the way the law works does have some merit, in not putting an undue burden on future development.
I hate the entire idea of the SACD DSD format, as I have heavily invested in digital audio equipment so I can do routing, equalization, and playback in PCM digital (or SPDIF/AES-EBU).
I hate pansy-ass moderators who go into discussion and moderate them down just because the content offends their sensibilities.
If it is a reply to a post, even if that post is off topic, THEN ITS FUCKING ON TOPIC, especially if it is rated 2, because the only way it will be seen is if you are reading that discussion.
Nope. Companies are under no obligation to provide you with a method for making backups; the AHRA or other laws may empower you to make them but don't set requirements on the feasibility of doing such an act. AFAIK.
This is actually quite reasonable, as where does one draw the line? SACD has a format incompatible with modern digital recorders...does this mean technology providers should have to recompense damaged purchasers or buy them all new hardware?
I think it is a register that is set in the NTSC encoder...so you could set the bit with a PIC or similar. You'd probably have to intercept the control signals to the encoder and only pass the ones you wanted to pass.
I guess if you *really* needed to strip it out you could this way. Sounds like a good bit of work though.
I think Firewire is cool, but currently video over Firewire means DV. DV is a huge improvement over analog videocameras, but it samples below the 4:2:2 or better one would like to see in HD applications. Probably one needs 400Mbps firewire to do reasonably good HD digital.
And the content controllers/still/ won't let us have it. Food for thought.
Well, I don't have a webpage out on it yet, but it shouldn't be too hard to take a look at the datasheets for, oh,
CS8414 ($8) and CS8405 ($4)
or
DIR1703 ($4) and CS8405
or use some of the other Crystal parts. Presto, 96kHz compatible bit-stripping. The bit-stripping is simply a matter of asserting Copy Permitted for all data rather than connecting all the lines like in the data sheet. You don't even need a crystal for 48kHz operation.
Most (virtually all) HD content though is analog at the point of connection to the TV. This is probably because manufacturers want to make "HD-ready" TVs without the added $500 cost of the ATSC decoders.
I know of no progressive-output DVD player which delivers digital content. At least nominally, this IS digital HD content delivered over analog signals.
In a sense, TiVo units do have DRM. They detect Macrovision on the incoming signal, strip it out, and add a flag to the recording that says "this had macrovision." Then when they output the signal they add macrovision encoding to content that has the flag set.
I'm not an expert, but I've heard that your ears do some modulation of audible signals by the reflected waveforms' content when it is >20kHz. So there is certainly some 'audible' component of the inaudible reflection, even if you aren't truly hearing the high freqency sound.
This may not be relevant in most setups though, to answer the parent's question. My DAC has a corner freqency of 50kHz on the low pass filter, but my amp starts to roll off at 30kHz. There are good reasons for this, such as white noise's power law and amplifier stability. You also have to be concerned about having a high corner frequency (96kHz) because your filter will not have much rejection of images of low frequency (32kHz) input. An ASRC with good image rejection is a possible solution to this dilemma, but causes its own problems.
A different advantage is the granularity of sampling is greater even at lower frequencies. There are many cases where the Nyquist sampling rate (2xFs) does not yield the expected results. Possibly minor in practice, but people are always striving for that Nth degree of quality.
Many S/PDIF recievers assume 24 bits of digital audio, possibly to their dismay if the format IS professional and those bits are carrying sync or other data.
However, you will in theory never hook up an AES/EBU stream to a S/PDIF reciever since the formats are, as you say, different electrically and (usually) mechanically. (balanced 1/4" or XLR)
A note to the AC (parent)...these are digital signals. Don't use something like INA137 which is an audio differential line reciever. Use digital ICs. They are cheaper and will have a much more beneficial effect on your jitter.
A domain I wanted had been expired for about 8 months. I wrote to NetSol about 3 times, got a single reply that said that no information was available since I was not the registering party...DUH, the name was EXPIRED. There wasn't a re
The day after I sent my third email the WHOIS information became unavailable, but I still couldn't register the name. The day after that a bulk domain reseller showed up in the WHOIS.
Also, access to direct digital streams is very important for high-end audio. Stray from the standard, and suddenly recording shops and the audiophile press are unable to use their $10,000 DACs...and are forced to use the $5 one contained in the average CD-player.
These people will yell bloody murder when (if) that happens.
Contrary to popular opinion, I think succintly reproducing small portions of articles can be helpful. For example, I didn't read the article, but wanted to browse the discussion. The fact was pertinent, succinct, and didn't interrupt the discussion at large.
Have you ever actually played SC:BW? There are many, many strategies that work. The thing that makes the game so interesting is that there is no such thing as a "winning" strategy: against a good opponent it comes down to economics (do more cost in damage to your opponent than the cost of your units) and risk-taking/luck.
Believe me, every time I've seen an "unstoppable" build order, strat, etc it's been fun for a bit figuring out a counter...but there always is one.

of course, the quality sucks, but to each their own...

Actually you can build your own SCMS-killer for about $11.
Maybe you should have read the article. One, I believe your efficiency rating is incorrect, and two, the design in question does not use solar cells.

My Philips 825 (c. 1999?) is flash-upgradable. I've done it, through a process just like the one you describe. I'm sure there are others.
However, I doubt this ever becomes a mainstream way to roll out upgrades. Burning a CD and flashing a new ROM is simply beyond most users.
The FAQ represents the opinions of the people that run /. I happen to have my own, thanks very much.
