Transistor theory - a reprise
In article , writes... Hi, Would you please tell me what transistor do and how to do so? What is the difference between PNP transistor and NPN transistor? What is the concept of using a transistor as a switch? Thanks a lot. SemiConductor Theory -------------------- (c) 1997 by Gareth Alun Evans A transistor is rather like the human alimentary canal, after the typical USA diet of burgers and chips; - it constipates, as do semiconductor diodes with no applied bias - the available holes get filled in and nothing can move. The base current is like a small application of laxative; some of the constipation passes through, until the effect of the laxative wears off. The total throughput depends upon the Mobility. By applying a continuous feed of laxative, then a continuous current passes through. Applying too much laxative results in saturation - ie, there is a limit to the maximum throughput, depending on the external circuit; in this case, the maximum rate at which you can feed in the burgers at one end. (If you are a customer of MacDonalds's, here in Chippenham, Wiltshire, UK then this rate is very low - I have been there twice, and both times, the service was *APPALLING*.) The difference between PNP and NPN is the direction. In the old days, PNP was used, whereby one injected from the rear end, using a sort of huge syringe - hence PNP - "Put-in Near Poo". More recently NPN is more common, where the laxative is entered via a carrier of some sort, usually chocolate and so we have NPN - "Now Pleasant Nutrient". Despite the adverse effects, the USA diet of burgers and chips carries on, and recourse has to be made once again to the chocolate. Now the ratio of the carriers of the constipation, the burgers and chips, is much higher than that of the chocolate. Thus they are referred to as the Majority Carriers and the Minority Carriers. If you indulge too much, you find that the vendor will provide you with a paper bag, known as an Excess Carrier. More recently, there are problems with impurities and you find that the opposite effect occurs. You have no time to reach home before diarrhoea takes over. You have no option but to stop the car and nip over a gate into a field. Hence the Field Effect Transistor. This time you have to inject something to STOP the flow. Now, assuming that there was a certain control over events; nothing happened until the Gate was encountered, you then became the Source of flow, and the field itself acted as the Drain. What was originally dirt, became grass, was consumed by the Cow, you ate it as a burger, and it has now returned to the topsoil, an effect known in the trade as Surface Recombination. (Incidentally, did you know that Diarrhoea is hereditary? Apparently it runs in the jeans.) Some of the impurities accumulate in your rear end, and no matter how valiently you try, you cannot rid yourself of them. Hence In-de-Bum is known as a Try-Valient Impurity. In the same way, Arse-nic, well known for its ill-effects and accumulation in the body tissues is known as a Pent-Up-Valient Impurity. -- 73's etc de Gareth G4SDW (ne G8DXY) GQRP 3339 |

b.com... That's the most bizarre explanation of any electrical effect I have ever seen! Well done. Well, actually, I did two on the same "theme" ... Alimentary Fourier Anal-ysis ---------------------------- (C) Copyright 1997 Gareth Alun Evans G4SDW The Fourier Transform is rather like the Human Alimentary canal.... The Alimentary Canal takes food, and then transforms it into something that is a function of the rear end, and hence may be referred to as, "The Food-Rear Transform". The Fourier Transform causes integration over a one second period, and results in an infinite series of sines. The Food-Rear Transform causes disintegration over a 12-hour period, and results in an infinite series of signs...."Gents", "Ladies", "Rest Room", etc. etc. The Fourier Transform (Tukey's reasoning?) takes Time and transforms it to a frequency spectrum. The Food-Rear Transform takes Parsley, Sage and Thyme (Turkey's seasoning?) and transforms it to a frequently active rectum. "Laplace", literally, "The Place", is how you deal with the transform. "Walsh" is something you do to your hands afterwards. "JPeg" is what you hang your jacket on to. It is a form of compression such that you take up less space and spend less time there (although the output may be more granular). The Fast Fourier Transform must be done through an appropriate window, otherwise an effect known as the "Picket Fence" problem, also known as "Spectral Leakage", can occur. Diarrhoea is known as the FAST Food-Rear Transform, and if done through the wrong window can result in a problem (also known as Rectal Leakage) all over the Picket Fence. The Picket Fence problem is also known as, "Scalloping", something which is normally done to pie crusts. In the old days, pies used to be made with "Four And Twenty Blackbirds"; but nowadays, members of the Jay family are used. When you go to someone's house for tea, you politely eat everything that is put in front of you, but your reaction might be, "Eat the Jay (Oh my God!) Tea???". Similarly, the Fourier Transform is a great consumer of e^(jwT)... "E to the j, omega, t". The Fast Fourier Transform is famous for its Butterflies. The Fast Food-Rear Transform is famous for its Butterflies-in-the-stomach. Dirichlet's are the Fourier Transform's conditions, without which the result is divergent. Diarrhoea ****s are the Food-Rear's conditions, with which the result is VERY divergent. Having experienced the Fast Fourier Transform, you are then faced with the Inverse, which can be very daunting. It is a paper exercise but it can be quite messy. Having experienced the Fast Food-Rear Transform, you are then faced with the "In Verde", literally "In The Grass", which can be very daunting indeed. (The paper exercise can be quite messy.) |
