[time-nuts] Dr Kinali

[Magnus Danielson]

Dear fellow time-nuts,

I just saw the PhD defense of Attila Kinali, which was succsessful and 
render him being Dr. Kinali.

It is interesting in that it shows that the Fourier transform 
traditionally used in engineering is not properly done as viewed in 
mathematical strictness. Through the formalism of math he redefines a 
Fourier transform that does work in a mathematical sense while being 
consistent with the traditional one and hence useful. The key issue is 
that some functions tend to integrate to infinity while they are in fact 
power limited, so it's only the length of integration that scales them 
to infinity. This is where engineering use cheats but a math strict 
approach cannot cheat.

He also visited a look at noise models and how these affect predicitions 
of noise of out amplifiers, with illustrations on how that now is used 
to better model actual noise performance.

Further he analysed meta stability of digital circuits and discussed those.

Overall an impressive thesis, not to say there is not to research on, as 
there is and several topics was discussed durign the defense, as it should.

Congratulations! Very well executed and performed!

Had conditions been better, I would have been physically present as 
originally planned.

Cheers,
Magnus
