What is effect on amplifier gain when is removed from the circuit?

It must (i) increase, or (ii) decrease, or (iii) stay the same.
If (iii), there's no point in having it at all,
so consider what happens to stage gain at the lowest frequencies, as the capacitor has less and less effect on the circuit.

What is effect of an unbypassed resistor on the common emitter amplifier circuit?
An emitter resistor in a common emitter circuit will cause the stage to experience the effects of degenerative feedback if it is unbypassed. The degenerative feedback reduces gain. This is probably the primary effect in the described circuit.
What is the purpose of having an lc circuit in an amplifier?
Because , ic can provide :- 1. very high gain 2. compact & less bulky circuit
What is the effect on the voltage gain of the circuit if different frequency values were to be used?

What is the effect of feed back on gain?
A: Number one it provide stability for the amplifier or system. The greater the feedback the greater the stability but less gain. In other words gain is inversely related to feedback
How op amp works as oscillator?
oscillator needs positive feedback in order to produce the undamped oscillations .This is done with help of he amplifier circuit.The oscillations are produced by the tank circuit cosisting of inductor and capacitor.The output of this tank circuit is fedback to the transistor which amplifies it and give back to the tank circuit input.If the gain of the circuit consisting of tank circuit and amplifier is more than one and the feedback given to tank circuit is in phase then we get undamped scillations as the output.

What is the effect of Rs and RL on the voltage gain of an amplifier?
it reduces the gain
What is a programmable gain amplifier?
A programmable gain amplifier (PGA) is a electrical circuit that allows the controller (user, machine) to adjust its transfer function so as to provide larger or lesser voltage gain. Usually it is a simple circuit, using an operational amplifier with negative feedback. In the negative feedback loop, several resistors and switches open and close, in order to achieve the desirable gain.
What is meant by swamped amplifier?
A swamped amplifier has a resistance tied to the emitter of the NPN transistor. Swamping the amplifier reduces the voltage gain. When an amplifier is swamped the voltage gain to the output is less dependent on the load. This helps to balance the output and protect the circuit when different loads might be applied.
What is effect of load on voltage gain of common emitter amplifier?
it makes sound :) trollolololol
What is the effect on voltage gain in a common emitter amplifier when the decoupling capacitor is removed?
The emitter bypass capacitor, in a typical common emitter configuration, increases gain as a function of frequency, making a high pass filter. Removing the capacitor will remove the gain component due to frequency, and the amplifier will degrade to its DC characteristics.
Who is more gain amplifier cascaded amplifier or darlington amplifier?
Darlington amplifier has more gain when compared to cascade amplifier .

What is voltage follower?
A voltage buffer amplifier is used to transfer a voltage from a first circuit, having a high output impedance level, to a second circuit with a low input impedance level.If the voltage is transferred unchanged (the voltage gain Av is 1), the amplifier is a unity gain buffer; also known as a voltage follower because the output voltage follows or tracks the input voltage. Although the voltage gain of a voltage buffer amplifier may be (approximately) unity, it usually provides considerable current gain and thus power gain
Need of multistage amplifier?
The Gain provided by the multistage amplifier is greater than the gain of single stage amplifier. The gain of the two stage amplifier is the product of the gain of the individual stages.
What is buffer amplifier and its applications?
A buffer amplifier is a type of operational amplifier that amplifies your input signal with a gain of 1 (so your output will be identical to your input, voltage-wise). Buffer amplifiers are used commonly due to having a very high input impedance. This means that loading effects (external factors that your circuit has to deal with) like large currents that could mess with your circuit otherwise, are avoided. A buffer amplifier is often used as the first stage of a circuit because it effectively isolates your circuit from loading effects.
