12WPM..... You keep sneering about this "Big K" on the assumption, or even a declared desperate wish on your part, that I'm wound up by it. I'm afraid that you are mistaken, but continue to make yourself appear to be a somewhat immature silly fool on the issue. I'm quite willing to challenge you on your infantility for as long as you wish to keep it up; indeed, that infantility is useful for it shows that all those who are associated in any way with the gangrenous degeneration that is the M3/CB Fools' Licence scheme, either as licensees or as L.I.A.R.s will _NEVER_ make it into the ranks of _REAL_ Radio Hams with their gentlemanly traditions. I've always been keen on technical matters and in learning thereof, and have never had any difficulty in admitting my own misunderstandings. (You're going to have a hard time as a teacher, BTW, if you sneer at those who are quite open about ignorance and their willingness to be taught) You're obssessed with "Big K", but seem incapable of discussing the technical issues. OK, let me help you......(and I'm confident that the folks in comp.dsp will be really really pleased with you for dragging this subject up again) Many texts and websites associated with DSP try to claim that the action of sampling is represented by the multiplication of the incoming waveform by a Shah function. Now, although the Dirac Delta Function is a very useful analytic tool once a network has been reduced to a mathematical equation, it is far from respectable to claim that such Delta Functions feature in the circuits used for sampling because no pulses of heights approaching infinity or of areas approaching unity, appear anywhere in the sampling circuitry. Therefore I suggested that some other scaling factor must be employed, that I dubbed "Big K". You, Brian, have sneered about this vacuously for some years now, but have been incapable of explaining why you sneer despite your _BOAST_ of having _TWO_ degrees, one in mathematics and the other in electronics. That alone is a sad condemnation of the standards of teachers in Strood, Kent, Britland. Perhaps you should lay off the whiskey that you keep discussing on Usenet? I have since discovered, by an embarrassingly simple explanation that the proposal of "Big K" was technically sound. "Big K" is no more than the sampling interval, normally shown as "T". Buttocks-Johnstone (or some such similar name, sorry don't recall what it is) in his treatment of sampling stated quite clearly that this T factor was necessary (in order to make the reconstruction maths work out) but even he couldn't explain where it came from, and to state that a factor is necessary to make the answer come out correct is a piss-poor (M3OSN-poor?) demonstration of technical acumen. The various text books and websites that discuss sampling continue to omit this crucial factor of T, so, if you were trying to resolve this difficulty, as I was, you repeatedly came up against the nonsensical assertion that sampling was the multiplication of an input waveform by a Shah function. Brian - you claimed that the answer was given to me quite early on in my Usenet enquiries, but I've not found such an explanation of the derivation .....perhaps you could now quote this answer?

Grow up, Eric! I can best deal with the Childish Broadcast (CB) of the rather silly and infantile child below by re-iterating one of the threads of the past few days.... "On a daily basis, this NG is a forum seemingly for escapees from the school playground, with gratuitous and offensive personal remarks originating from even those who have not been part of a conversation and who could have no reason, other than uncontrolled infantile emotions, for interjecting as they do. Is such public and international demonstrations really the way forward; the way for PR for the future of Ham Radio. I say, "No!". I cannot see how something that is a technical pursuit with traditions of gentlemanly behaviour could possibly give way to the childish sneering that is typical of this NG."

Then again, maybe it is something else that has you so prickley. Far be it from me to wind you up, please continue to believe your confabulations, if it makes you happy. Good night. Brian
