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 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.
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 hie for a transistor?
hie is input impedance when signal applied at its base.
Why transistor is called transfer of resistor?
Transistor=Transfer+Resistor. When Transistor operates in active region its input resistance is high and output resistance is low. So,We can consider transistor as a device which transfers its resistance from high to low. And by this property transistor amplifies input signal.
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.
Can transistor be used to increase the strength of an ac signal?
Yes, a transistor can amplifiy an a.c. signal.
How is current amplified in a transistor?
Transistor increase the strength of a weak signal from the base
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
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.
How do you convert npn signal to pnp signal?
To convert an NPN signal to a PNP signal, you can use an inverter circuit, typically implemented with a transistor or a logic gate. For a simple transistor-based solution, connect the NPN transistor's collector to the power supply, its emitter to the load, and the base to the NPN signal through a resistor. When the NPN is on (high signal), it will turn off the PNP transistor, resulting in a low output, and vice versa, effectively inverting the signal.
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 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 you use signal generator to test transistor?
To test a transistor using a signal generator, first configure the signal generator to output a small AC signal at a specified frequency, typically in the audio range. Connect the generator's output to the base (for BJT) or gate (for FET) of the transistor while grounding the emitter/source and collector/drain appropriately. Measure the output at the collector/drain with an oscilloscope to observe the transistor's amplification characteristics. By analyzing the output waveform and its relation to the input signal, you can assess the transistor's performance and functionality.
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.
What are the two main uses of a transistor?
a) to act as a switching device; a change in the bias voltage at the base- emitter junction can cause an increase in signal flowing through the transistor through the collector terminal and this cause the output voltage at the collector terminal to change; eg to drop to a low voltage level, this is seen as the transistor device switching on to maximum conduction rate and a low level output at the collector. b) to act an amplifer . whether the input signal is an ac type signal in which case its a signal power amplifer function; eg sound amplifer control circuits , or whether a dc input signal, in which case the input dc signal is amplfied to be reproduced as a bigger signal at the output collector terminal
