Any experience with negative impedance?

In which case, it should rightfully be called the DeciMeucci.

About time that guy got something named after him. Bell doesn't deserve approbation.

Irrelevant outside of the UK.

Another stupid Euorpeon heard from. Do you have any idea what the word "an" means? I want *THE*. ...what an idiot...

The original poster was ridiculing my use of the expression "official publication" There is no higher authority in the UK than the monarch and, in 1938, His Majesty's Stationery Office was the official organ for publishing national and international standards. This gave the American (Bell System) definition of the decibel the full weight of UK acceptance

- there could not be a more "official" way of endorsing it than that.

If you think that the UK standards system is irrelevant, presumably the same applies to American standards (anywhere outside America) and we may as well forget about international standards and all go our own way.

I had hoped that your ignorance wasn't genuine. As it now appears to be the real thing, and you seem to have brought it to an unusually high state of perfection, I can see why you feel proud to flaunt it so blatently.

Quite true. Neither the British Standards Institution, or the National Institute of Standards and Technology have any authority outside the UK, and USA, respectively.

The British Admiralty Handbook you quoted had no regulatory authority outside the Royal Navy, and its contractors, let alone the UK as a whole.

According to Wikipedia, the decibel was defined in the NBS(predecessor to NIST)yearbook of 1931, seven years prior to your reference.

*International* standards are the province of the ISO.

Try reading again, this time for comprehension. You said "An official publication". There are *millions* of "official" publications. I was laughing *at* you because you thought it was somehow *the* "official publication". The fact that you don't know the difference, is sad.

Good Lord, anyone who believes that claptrap is hopeless.

The UK is about as irrelevant as irrelevant can get.

Clearly you don't know the meaning of that word, either. I take it that English isn't your first language.

You get your ass caught in a crack of your making and blame others. Typical Eurotrash.

Although in this case all the HMSO Navy book does is reference an established measurement standard based on work at Bell Labs in the USA.

Had they been waxing lyrical about the convenience of the Jar as a standard measure of capacitance then you might have had a point.

Brain dead people are much easier to control however, when it gets to that point, is when the kingdom comes tumbling down and all the politicians will blame the little people for being brain dead.

You see, it's a double edged sword, it only ends when the corrupted politicians (that's most of them) end.

It's not surprising since I'm often responding to your idiocy.
