TRANSISTOR AMPLIFIERS EXPERIMENT
Experiment: Transistor Circuit Design - Backyard Brains
Experiment: Transistor Circuit Design. You can now explain with confidence what p-doping, n-doping, and depletion layers mean. Now you will put that knowledge to use. You have the transistor in your hand. You stare at it, knowing the power it contains and what it has done for the world. Here you will use your transistor to amplify some spikes.

A PNP transistor can be paired with an NPN in simple audio amplifiers to make a headphone or speaker amplifier. The PNP complement to the 2N3904 is the 2N3906. Figure 9 shows how a 2N3906 might be used to create a negative bias voltage in a system with only a positive supply.
What is Transistor, History and Symbols | Vacuum Tubes
In December, 1947 their experiment with two gold contacts applied to the germanium crystal produced an output signal power greater than the input signal. Thus the first transistor technology developed was known as point contact device and this technology was regulated by higher performance types.

Transistor Tutorial about Bipolar and FET Transistors
The Bipolar Junction Transistor (BJT) is a three layer device constructed form two semiconductor diode junctions joined together, one forward biased and one reverse biased.; There are two main types of bipolar junction transistors, (BJT) the NPN and the PNP transistor.; Bipolar junction transistors are “Current Operated Devices” where a much smaller Base current causes a larger Emitter to
Bipolar Junction Transistor (BJT) Viva Questions and
A transistor has three terminals namely emitter, base and collector. A transistor is a current sensing device. Transistor was developed in the year 1948 at BELL laboratories. A transistor can be seen as two p-n junction placed back to back. The emitter is heavily doped, while the base is lightly doped. The collector is moderately doped.
RC Coupled Amplifier Basics, Types, Response & its Experiment
This experiment of the RC coupled amplifier can be performed with the basic resistors and the capacitors with the transistor circuit. So let us discuss the experiment in detail. Aim: the purpose of the experiment is to obtain the frequency response and the gain of voltage for the RC coupled amplifier.

In domestic system amplifiers the loudness level is simply adjusted with the Volume control. pic is a simple circuit that will actually work and is an ideal beginning for electronic students to construct and experiment with to obtain an understanding of the basic principles. is described as a differential input. The 3rd PNP transistor
Gyrotron - Wikipedia
A gyrotron is a class of high-power linear-beam vacuum tubes which generates millimeter-wave electromagnetic waves by the cyclotron resonance of electrons in a strong magnetic fieldut frequencies range from about 20 to 527 GHz, covering wavelengths from microwave to the edge of the terahertz gapcal output powers range from tens of kilowatts to 1–2 megawatts.
