What is the work of transistor?
The work of a transistor is to amplify the input signal to get high output value.
Why is a transistor an active element?
Transistor is an active element because it can amplify the signal applied.
What is Bias circuit?
in reverse bais negative terminal of battery is connected to p section and positive terminal to n section that arrangement is called reverse bais.Answer given by Sehdev Kumar B.Teh. 1st year
What is unmodulated signal from a transistor is called?
When the out from a transistor is the exact replic of the input signal then it is called unmodulated signal i e. there will not be any change in frequency voltage power etc
When transistor acts as an amplifier then does its output voltage increase or decrease?
That depends on both the input signal and the type of amplifier the transistor is used in.
What is difference between transistor and bias?
"Biasing" applies to transistor amplifier circuits. Simple amplifier circuits can only amplify positive signals. Negative signals cause the amplifier to shut down. However, AC signals in general have both a positive and a negative part. To allow a transistor to amplify AC, we add a positive voltage to the AC signal. Then after it is amplified, we remove the positive voltage again. The voltage, ac or dc on the base, compared to the emitter to cause operation of the transistor to conduct to the collector or to the emiiter in a NPN transistor.
In amplifier is voltage amplify or only signal of voltage amplify Please give answer in simple englisH IN SIMPLE English an amplifier doesn't need to amplfy any signal to be an amplifier it can be us?
I think Amplifier is use for direct signal or D.C signal & the main function of amplifier is to make that signal sharp(powerful) so that a microprocesser process it.
What are the active electronic components?
Active devices are those devices which can produce power or which can amplify the signal Such devices are- diode transistor op-amp
What is description of Bc547 transistor?
BC547is an NPN bi-polar junction transistor. A transistor, stands for transfer of resistance, is commonly used to amplify current. A small current at its base controls a larger current at collector & emitter terminals.BC547is mainly used for amplification and switching purposes. It has a maximum current gain of 800. Its equivalent transistors are BC548 and BC549.The transistor terminals require a fixed DC voltage to operate in the desired region of its characteristic curves. This is known as the biasing. For amplification applications, the transistor is biased such that it is partly on for all input conditions. The input signal at base is amplified and taken at the emitter. BC547 is used in common emitter configuration for amplifiers. The voltage divider is the commonly used biasing mode. For switching applications, transistor is biased so that it remains fully on if there is a signal at its base. In the absence of base signal, it gets completely off.
What is the best way to describe the function of a typical transistor in an electronic circuit?
A transistor in a circuit can do many things. It can be used to amplify voltage signals, or current signals, create current and voltage sources, make buffers, and so on. Transistors also find a major use in logic circuits (ie, where signals can either be a '0' or a '1'), where they essentially act as a switch, and can be used to create inverters, AND gates, OR gates, and all sorts of useful components. By itself, a transistor is a three-terminal device that can control the current going through two of its terminals through the voltage applied at the third terminal. But there are many applications for a transistor in its many different configurations, which is why it is so important in modern electronic technology.
Will semiconductors amplify the electric signal in a transistor?
Actually, a transistor is a device made from semiconductor material, and they're used to amplify and switch electronic signals as well as electrical power. Before transistors were invented, product engineers had to use vacuum tubes and electromechanical switches in order to complete electric circuits.
What is a mid point bias in a transistor?
Midpoint bias in a transistor refers to a biasing technique that sets the operating point of a transistor at the midpoint of its output characteristics. This approach ensures that the transistor can amplify both the positive and negative halves of an input signal without distortion, maximizing its linear operation. By positioning the quiescent point (Q-point) in the middle of the linear region, it allows for symmetrical swing around this point, enhancing performance in amplifier circuits.
