What is the output signal of a common base amplifier?
3Db
What does an amplifier do to a small input signal?
amplifier will strengthen da small input signal n amplifies it
What type of signal at the NPN output?
A: It always a voltage since it is a voltage amplifier
Amplifier voltage gain is 15db input signal is .8V what is output voltage?
54.6dB
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 Op-Amp non inverting amplifier?
When the feedback of the output terminal of an Op-Amp is given to the non-inverting terminal [pin 3 for IC-741] of that Op-Amp , then , that circuit is called non-inverting amplifier using Op-Amp. This circuit is called non-inverting because the output signal of this circuit is in phase with the input signal.

Are amplifiers input or output devices?
An amplifier is both an input and output device. An amplifier, as its name suggests, amplifies a signal, meaning that it makes it stronger. An amplifier takes something as input, like maybe a sound signal, and its output is a more powerful (or louder) version of the same signal.
What is the ratio of the output signal to the input signal of an amplifier that is usually measured in decibels?
Answer is GAIN
What is use of negative feedback in amplifier?
Reduce the distortion in output signal.
Why is the output signal affected if the impedance of the amplifier and the load do not match?
A: The signal output will not change it is just that the efficiency of power transfer is effected to less
What is the use of operational amplifiers in circuits?
An operational amplifier is typically used where it is desirable to control a voltage over a wide range of levels; i.e., in analog mode as opposed to the on-off limits of a digital signal. An operational amplifier in simplest form will have a non-inverting and an inverting input terminal and an output terminal, each of which are analog in function. The output terminal will tie into external circuit components that eventually connect back to the inverting terminal. The key to its performance is that when a change is made to the voltage on the non-inverting input terminal, the output of the amplifier will change in voltage level, whether increasing or decreasing, to the level that causes the voltage appearing at the inverting terminal to equal that of the non-inverting terminal. In that way the output voltage is a predictible value that is useful for automatically controlling a flow valve or other device. Of course, it can also be used to just to act as a signal conditioner for sensors, audio devices and countless other applications.
What is the ideal dc value of output signal when there is no input signal in class b amplifier?
A: If the input is zero the desire output is zero no matter what class it is.
What type of signal at the NPN output?
A: It always a voltage since it is a voltage amplifier
Am amplifier that inverts the signal between input and output is called a what?
common emitter
Amplifier voltage gain is 15db input signal is .8V what is output voltage?
54.6dB
