TI degrading specs of existing parts without changing part numbers

You made the claim, you do the googling.

It's even richer with people saying "that's not possible" and turning out to be right.

Jeff Liebermann dug out the example.

You do seem to be hell-bent on maintaining your reputation as a gullible twit.

FYI: Speed of sound is 340.29 m / s

In a nano-second sound moves: 340.29 * 10^-9 = 3.4029e-07 meter or 3.4029e-07 * 1000 = 0.00034029 milimeter Even a 1 degree phase shift is 1/360 so about 0.000001 mm, distance between 2 neurons.. hairs in the ear?

Not even counting <MAKING the sound. Beep!

You can express Any Sing in nano seconds !!!

BTW the signal from the nerves in the ear to the brain takes orders of magnitude more time

Drop your nano nano obsession!!!

Did you not got hit by crocodile sounds once? There is a survival series here on TV every sunday .. those guys catch alligators with a hook and same bait. I now know how to catch and kill an alligator!

Done ANYTHING with sound ever?

I use nanoseconds (or pico of femto) to describe anything below a microsecond. I do have old books that use millimicrosecond units, or micromicrofarad, uuF.

The prop delay between your wrist and your brain obviously makes it impossible to play tennis.

My favorite expert-impossible was fathead boffins declaring that a biological rotating motor was impossible. I think there is one that runs something like 100K RPM. We would not have babies without a spinning molecular machine.

We helped discover some infrasonic croc calls, yes.

I designed a guitar amp once, the Ryder 200 or 500 or something. Named after a buddy, Frank Ryder. He wised up and married a rich German girl and got out of audio.

And of course I designed the things that found the alligator calls in Mississippi.

Oh, and the paging system for the New York City subway. Not very hi-fi.

I don't like music and audio is boring and low profit, so I prefer picosecond stuff.

Why? those balls do not fly FTL or even faster then sound! I cannot play tennis anyways... Football: yes, been a long time though. Hockey in school days And Chess too. Won from a local champ once, that really pissed him off.

Nature has a lot we still need to discover. Will the next generations come from a tube? Or just be computer chips and no more humans? Or use a 'Design you own kid' Walmart box?

I designed a (tube in those dayhs) guitar audio amp for the school band, they liked it. Later I got contacted by one of the players, he wanted special effect stuff too.

Build nice 3055 amps too for at home, and then when in broadcasting designed some audio stuff. It is quite something to get audio right with all those bands and artists no errors allowed. We did film stuff too. Relayed Euro Vision songfestival, head control room. No errors allowed. Moonlandings the same politicians.. what not.

Impressive.

Well 'no profit' the Beatles were one of my favorite groups, they did get very rich I think? Bob Dylan music I still have (now in mp3 ;-)), he got a Nobel prize for his music.

I like music, was just listening to 'I Will Always Love You' by Whitney Houston

As to sound and ultrasound: I have published lots of stuff in this newsgroup over the years.

If I press record too late I only get the end part of the song

mp2 audio!!!

Poor Mr Hobbs

Probably have all of it or more of this on some harddisc

Seems most is on youtube anyways these days, you can download that via some sites.

In my neck of the woods, when you rhetorically quote some spec in the

The numbers that were cited were all for timing in nanoseconds and NOT for distance as in nanometers.

Incidentally, I've read through various papers that mention the 10 nsec number. The majority refer to a 10 nsec jitter and NOT a 10 nsec resolution. Also, the 10 nsec number seems to be at the extreme edge when graphs were supplied. My guess(tm) is that there might be some confusion between 10 nsec jitter and nsec resolution in some of the various papers. For example:

"Delay accuracy in bat sonar is related to the reciprocal of normalized echo bandwidth, or Q"

I couldn't determine what the author meant by a "small fraction of a microsecond".

So that's a source of the 10ns stuff. The theory is that there was an instrumentation error, which is certainly plausible as no biological system is that fast, so biological researchers are far out of their domain for sure.

PS: The 100,000 rpm spinner in biology is "ATP Synthase", the enzyme system that converts between ADP and ATP in the mitochondria (in animals) and chloroplasts (in plants).

Why do you say that no biological system can be that fast?

Anything less than a microsecond is astounding, inside the gooey head of a bat flapping its wings mid-air hunting a moth.

DNA helicase, the little gadget that splits our DNA when a cell divides, spins at about 10,000 RPM.

Google the <> above.

It's only my best guess(tm). I didn't have much success at finding the oldest bat related citation that included a 10 nsec response time.

Sigh. I initially mentioned that there might have been some confusion between response time and jitter. Now, you add DNA replication to the confusion. Time for a sanity check.

What got my attention was the radical difference between the alleged

"Nerve conduction velocity"

I once watched a "cloud" of fruit bats emerging from the trees at dusk:

To put it in perspective, a microsecond at the velocity of sound in air corresponds to 0.25mm (or 0.125mm for echolocation distance measurement).

The resolution would be the time-difference between two pulses and could possibly be resolved to 10nSec if the delay times were equal (or equalised). Prediction, based on existing trajectories, is a more likely explanation.

They measure what's easy to measure, an electrical impulse. Maybe that's not the information being sent.

Bats catch moths. Baseballs get hit.

If nerve impulses travel 100 m/s and a bat's ears are 2 cm apart, the neural delay between ears is 200 us. And that's modulated by movement, heartbeats, things like that.

Maybe nature doesn't care about our opinions of how it's allowed to work.

John Larkin Highland Tech Glen Canyon Design Center Lunatic Fringe Electronics

The electrical impulse isn't all that easy to measure, but at least it is visible, if you measure carefully enough.

You can hypothesise all sorts of magic connections, but until you spell out what one of them might be and how you'd measure it, you are just going in for hand-waving mysticism.

It all looks very as if you got caught being even stupider than usual, and are now trying to back off.

And half-wits have very silly ideas about what that implies.

Obviously it doesn't. That doesn't excuse you from picking up particularly half-baked ideas about how well it might be performing and posting them here.

True. Please note that the URL's I provided were not in response to your posting. I was responding to a question by snipped-for-privacy@comcast.net: Message-ID: snipped-for-privacy@4ax.com "Bats are pretty good, but that seems a bit too good. Can you find that study?"

Methinks the mechanism might be similar to measuring the speed of electrons in wires. Energy transmission in a wire moves at near light speed. Electron drift velocity in wires (the movement of individual electrons) is about 1 mm/sec, which is much slower. I suspected that nerve impulse transmission in bats might be similar. However, my analogy breaks down because nerve impulse velocity can be 1 to 100 meters/sec, which is still much slower than near light speed (3*10^8 meters/sec).

"Nerve conduction velocity"

"Bats are surprisingly fast decision makers"

Caroline Palmer's Ph.D. thesis is on the timing in skilled piano playing. I've got a copy.

We probably do as well as bats in our own areas of interest.

It's not hard to use an internet search engine. You could take a class.

Most ideas are half-baked at first. But hostility to ideas guarantees that you will have none.

We need more goofy ideas; lots more. Then we need to sift out the few good ones, not club them all to death on first sight.
