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 else can I help you with?
What electronic function made the transistor famous?
The importance of the Transistor was that it could amplify an electrical signal. It was thus an analog of the vacuum tube devices, and could take advantage of the circuit history and applications that had built up over the preceding 50 years.
What happens when high input signal is given to pnp transistor?
A high signal input to a transistor amplifier gives a high signal output provided it stays linear.
What are advantages and disadvantages of multistage amplifier?
to amplify a small signal to sufficient level,so that it can travel to a large distance from first stage till the last stage
What is a transistor that is normally on with no applied signal?
The PNP transistors conducts when there is no signal at base (0V or grounded), when base current is increased the conduction of PNP transistor decreases.
How do transistors amplify weak signal?
A transistor controls the flow of current between the emitter and collector. The larger current is supplied by the power supply, across the emitter and collector. The flow is then controlled by a small current applied to the base connection. So, a large current flow mimics the small signal current. Limits are reached, when the transistor gets close to being fully switched on or off. This will cause distortion. To avoid this, more amplification is provided by a series of transistor amplifiers, one after the other.
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.
Why you add a positive voltage to the ac signal to allow a transistor to amplify ac signal?
It depends on how you bias the transistor. If you ground the emitter, which is very common, you will need to offset the input signal so you can amplify the full voltage swing.
Which combination of n - type ( n ) and p - type ( p ) semiconductors would be used to amplify a weak electronic signal?
An n-p-n bipolar junction transistor (BJT) configuration is typically used to amplify weak electronic signals. In this configuration, the base region is p-type, sandwiched between two n-type regions (collector and emitter). This setup allows for the amplification of an input signal as it passes through the transistor.
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 the basic definition of a guitar amp?
An amplifier that is designed to amplify the signal from an electric guitar and drive a speaker to convert that signal to sound.
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 saturation and active region in a transistor?
The output current of a transistor is controlled by the current in the 'base' input: Increasing the control current will increase the output current in a more or less linear fashion. In the saturation region, this is no longer true: The transistor is nearing the limits of how much current it can conduct, so increasing the control current further has little or no effect. When using a transistor as an amplifier, you want to stay away from the saturation region as it would distort the signal you are amplifying. When using a transistor as an on/off switch, as in digital circuits, being in the saturated region is 'on' and a normal mode of operation.
What electronic function made the transistor famous?
The importance of the Transistor was that it could amplify an electrical signal. It was thus an analog of the vacuum tube devices, and could take advantage of the circuit history and applications that had built up over the preceding 50 years.
Can transistor be used to increase the strength of an ac signal?
Yes, a transistor can amplifiy an a.c. signal.
Is transistor linear or non linear?
A transistor can function in both linear and non-linear modes. In the linear mode, it can amplify small signals with a linear relationship between input and output. In the non-linear mode, the transistor operates as a switch, turning on or off based on the input signal.
Why amplifier is required?
Amplifiers are the device which are used to amplify a signal Multistage amplifier are use to amplify a signal into a desire level
