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 does amplifier do to a small input signal?
makes it bigger! (or sometimes smaller, or sometimes the same, but with lower output impedance)

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 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
