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.
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 biasing and connection?
Transistor biasing is a function of implementing a DC support circuit that places the transistor in an electrical region that produces the desired output signal in relation to its input signal, according to its design specification. A transistor can be biased to create a linear amplified signal proportional to its input. Biasing can also place the transistor into an easily saturated condition to propagate clipped binary output relative to its input. Biasing refers to the component configuration designed around a specific transistor family. Connection refers to the simple function of making an electrical junction between two conductors.
Why input gain of an amplifier is doubled from output gain?
The gain of a transister stage is determined by its biasing circuit design. The emitter of a transistor is affected by the input signal on the base. If the base forward biases the transistor, the emitter feels the potential of the colector. If the base reverse biases the transistor, the emitter is isolated from the collector and feels the potential of the emmiter biasing circuit. The output signal at the emmiter is representitive of the signal on the base, 180 degrees out of phase. The amplitude of the output signal will be larger, depending on the biasing circuit design.
What is the work of transistor?
The work of a transistor is to amplify the input signal to get high output value.
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

How does a transister work as an amplifier?
The name is your clue: a transistor and a resistor (the load) are put in series. The output signal is taken from the load resistor. A small input signal (to the third lead of the transistor) will cause the transistor to change resistance ... thus you can get a large output from a small input Amplification.

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.
In which transistor bias method is the input signal rectified?
in which of the following transistor bias methods is the input singel rectified? A. source biasing b.voltage divider biasing c.power supply biasing d.avc biasing
What is gate delays in transistor logic gates?
the gate delay is the time from applying the signal to the input and getting the signal at the output digital implies on or off so when the signal goes to the input it takes a bit of time to rise to a sufficient level to saturate the transistor there is also a bit of capacitance present so the transistor takes time to drain off all the charge the smaller the less delay
Why ordinary transistor is known as bipolar junction transistor?
Transistor is known as bipolar junction becoz it has 2 pole. Input is given to the 2 junction and output is taken from to junction
