Yes people still use bipolar junction transistors today because of its high switching speed.
Depression/Bipolar and ADD/ADHD is becoming more known among the American people.
Yes. Today's microprocessors have many, many times more transistors than those of the 1970's.
In fact, the antecessor of transistor was the diode. Transistor is an abbreviation for "Transfer resistor, A transistor is formed by the combination of two diodes,and the first diodes were made of germanium to allow current flows on one direction and blocking it on the reverse direction. Transistor was the basis for the real development of electronic technologies, but the main material inside of it, that started with germanium, today is used silicon, and graphene is the newest material that promises to replace silicon with many important physical features.
The no.of transistor integraeted in the prosses..................
It's not that rare, and a lot of people have it. Diseases that were rare back in the 1900's or so are becoming more well known today, such as cancer and other things including bipolar disorder.
Of course. Transistors are the base of all computer processors. They are the successor to the vacuum tube.http://en.wikipedia.org/wiki/Transistor
The transistor gave the technology world a huge boost, which is what originally started up modern computers today which use 32nanometer transistors that switch to 1 and to 0. Transistors have created the world we live in today that includes much more technologically advanced computers that get twice as fast each year. -Room for improvement-
The triple junction is a point where three tectonic plates meet. There are multiple triple junctions around the world, such as the Afar Triple Junction in Ethiopia and the Galapagos Triple Junction in the Pacific Ocean. The location of these triple junctions can change over time due to the movement of the tectonic plates.
Except for some technical terms (MRI, transistor, etc), the same words as today ... watch a few old movies and see for yourself.
There was a road accident today on the High Street at its junction with Hugh Lupus Street Bolton. There was a fault in the electrics, our electrician suspected a fault in the junction box. I'm lost, I think I should have left the Motorway at that last junction. Junction is the name of a fictional planet in the Dune universe.
People Livin' Today was created in 1992.
Transistors are semiconductor devices which can be used as switches (to turn on and off an electrical signal or current path) and also as a signal amplifier in a circuit. There are two broad types of transistors BJT (Bipolar Junction Transistor) and FET (Field Effect Transistors). - Neeraj Sharma A transistor is a silicon device with 3 leads, emiter, collector, and base. It is used both as a fast switching device and for signal amplification. It is said to be "saturated" when maximum current is flowing and "cutoff" when no current is flowing from the emiter to the collector. It takes a difference of approx. .7 volts between the emiter and base to turn it "on". Good switch but actually inferior in sound quality to its predicessor, the "Thermionic" or good ole vacuum tube. If you don't believe me, listen to a guitarist play through both a transistor and vacuum tube guitar amp. You will be quite amazed!!! For signal amplification the input signal goes into the base and the amplified output signal is taken at the collector with the transistor operating, or biased, between cutoff and saturation. It would be normally biased in between cutoff and saturation for the signal to be "linear" or non distorted. The signal at the collector will be inverted (180 phase shift) with respect to the input signal. There are other applications where the output is taken at the emiter where the signal is not inverted (in phase) with respect to the input signal. This configuration, generally, has no gain or has what is called "unity gain". Sometimes you see this when separate stages need to be impedance matched for maximum efficiency. The transistor is first "biased" or configured for a specific amount of gain and the output signal is taken at the collector with a higher amplitude than the input at the base. A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power . It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor's terminals changes the current through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power, a transistor can amplify a signal. Today, some transistors are packaged individually, but many more are found embedded in integrated circuits . The transistor is the fundamental building block of modern electronic devices, and is ubiquitous in modern electronic systems. Following its development in 1947 by John Bardeen , Walter Brattain , and William Shockley, the transistor revolutionized the field of electronics, and paved the way for smaller and cheaper radios, calculators, and computers, among other things. The transistor is on the list of IEEE milestones in electronics, and the inventors were jointly awarded the 1956 Nobel Prize in Physics for their achievement.
