Different between power transistor and transistor that used in small signal?
Power transistor can conduct large amount of currents through it, more than small signal transistor. power transistor has a vertical structure and small signal transistor has horizontal structure.In power transistor quasi saturation region is present which is absent in the small signal transistor. In power transistor there is a inculsion of drift layer which is not there in the small signal transistor. Power dissipation is less in power transistor and it is more in small signal transistor. b.v.polytechnic,vasai pushkar vaity.
What is an unbiased transistor?
An unbiased transistor is one being used with no bias voltage to offset its operating point. If the input signal is very small it still can operate as an amplifier but the output will be non-linear. One use for an unbiased transistor is when the transistor is used as a switch, turning it on or off.
Why are transistors used in circuits?
The two main functions of a transistor are: (a) signal amplification, and (b) solid-state switching.
When a transistor is used as an amplifier increasing the base current will cause an increase in?
Increasing base current causes a proportionate increase in collector current - proportionate to hFe, unless the transistor is operated outside of linear mode.
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.
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 the function of an amplifier in electronic communications?
An amplifier is used to increase the strength of the signal.

What is the electronic device that's used to increase the strength of the signal fed into it called?
Amplifier
Which of these is not a type of signal used to send information through electricity?
transistor
What is a cross coupled transistor?
A cross coupled transistor pair are used to increase the gain of the cell.
Why a transistor is called with BC547?
A small signal NPN transistor used for general purpose audio amplifiers and switching.
What is an unbiased transistor?
An unbiased transistor is one being used with no bias voltage to offset its operating point. If the input signal is very small it still can operate as an amplifier but the output will be non-linear. One use for an unbiased transistor is when the transistor is used as a switch, turning it on or off.
What is different about the method used to boost digital signal strength compared to the method used to boost analog signal strength?
A digital signal requires a repeater, which retransmits the signal in its original form, and an analog signal requires an amplifier, which increases the strength of both the signal and the noise it has accumulated.

What signal meter for ota Signal Strength?
The new digital TVs and Off-Air Converters have an On-Screen Signal Strength Meters available through the menu. This is used to help aim the antenna for the peak signal.
