The initial statement was: "lowest bits of a D/A converter are the most non-linear. By avoiding them you might get a more accurate waveform overall." You can of course apply dithering to any signal to mask quantization noise.

Sorry, but no! 1.0 1.1 1.9 2.0 2.1 2.9 3.0 is still a better approximation of a linearly increasing list of numbers than 1.0 1.0 2.0 2.0 2.0 3.0 3.0 and I doubt that any 24bit DAC or ADC in existence will interpolate as b

Typical DAW already run in floating point, as do most digital mixing consoles. It's only input/output to physical audio cards that's quantized to 24bit. If you want to "render", i.e. produce a final .wav file from y

You are overestimating the jitter problem by a large amount. The first S/PDIF receiver IC I find via google (CS8416) claims to have an output jitter of typ. 200ps on the clock output, running from its internal PLL synced to an extern

You are right, in that your guess is wrong ;-). Total activity decrease in realistic "atomic waste" is not at all exponential. Try a simple example: Take a mixture of two isotopes. The one isotope has a half-life of 1 year and the

Oh, but that's the whole idea of fracking. You inject (not necessarily polluted on purpose from the start, but it will be at some point if reused a few times) water under high pressure into the ground to break up sediment, releasing a

Sure enough. But is it a sane thing to do for a "convert readable date to date object" function to silently amend the current day-of-month to a otherwise underdpecified date? I really don't see the use case for that anywhere.

Yes, this would be smart. Probably just putting a message with priority "Error" in the windows event log would be enough to warn computer-literate users.

Has this been proven by a corresponding packet dump listing "Write EEPROM, offset 0, 4 bytes: [0,0,0,0]? Or are they -sneakily- bricking the device by evoking an unintended reaction to a seemingly innocuous command? The former will be
