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.

Amplifier voltage gain is 15db input signal is .8V what is output voltage?

What is stage gain in a C-E amplifier?
Stage gain in a common-emitter (C-E) amplifier refers to the amplification factor of the input signal as it passes through the amplifier stage. It is typically defined as the ratio of the output voltage to the input voltage, expressed as a voltage gain (Av). In a C-E configuration, the stage gain is generally greater than one, indicating that the output signal is amplified relative to the input. The gain is influenced by factors such as the transistor's characteristics, resistor values, and the load connected to the output.
How do you prove that the output of a differential amplifier is the difference of its two inputs?
A: By applying two known DC input with a known gain the output will be there to prove the difference.
What is the voltage gain of a transistor amplifier that has an output of 5 rms and an input of 250 mV rms?
The voltage gain (Av) of a transistor amplifier can be calculated using the formula ( Av = \frac{V_{out}}{V_{in}} ). In this case, the output voltage is 5 V rms and the input voltage is 250 mV rms (which is 0.25 V). Therefore, the voltage gain is ( Av = \frac{5}{0.25} = 20 ). This means the amplifier has a voltage gain of 20.
Why CB amplifier preferred for high frequency than CE amplifier?
1)in cc configuration we use to get the low output impedence where as in ce we use to get the high output impedence. 2)in cc amplifier we use to have the voltage gain equal to unity where as in ce amplifier we use to have the high voltage gain. 3)in cc amplifier there is high power gai which is used for impedence matching where as in ce amplifier due to the high voltage gain the impedence matching is less impossible.
Why does amplifier gain reduce?
Since we know that the amplifier gain is given by A=Output voltage/input voltage (where A is the amplifier gain) So, it can be written as output voltage=A*input voltage, so when the output part increases gain increases but when input part increases gain decreases
What is voltage gain?
Voltage gain is the ratio of the output voltage of an amplifier to its input voltage.
Power gain of an amplifier having input gain of 20W and what is the output gain of 20mW?
The power gain of an amplifier having an input of 20W and an output of 20mW is 0.001. Expressed in decibels, that is a gain of -30db. (log2 0.001 * 3)If you meant an output power of 20MW (mega instead of milli), the gain is 1,000,000, or +60db.
What is power gain of an amplifier having input gain 20watt and output of 20mwatt is?
The power gain of an amplifier having an input of 20W and an output of 20mW is 0.001. Expressed in decibels, that is a gain of -30db. (log2 0.001 * 3)If you meant an output power of 20MW (mega instead of milli), the gain is 1,000,000, or +60db.
What is the ratio of the output signal to the input signal of an amplifier that is usually measured in decibels?
Answer is GAIN
Amplifier voltage gain is 15db input signal is .8V what is output voltage?
54.6dB
Ratio or amplifier output signal to its input?
It never referred as ratio but Rather a gain A in the form of output divided by the input and implies voltage A=gain. basically is input resistance divided by the feedback resistance
What is gain on guitar amps?
Gain, usually measured in decibels, is the ratio of output to input power. A more sensitive amplifier will have higher gain settings requiring less input signal.

What are the characteristics of a common emitter amplifier?
There are a number of characteristics found in a common emitter amplifier. Not only are the parameters considered, but also their performance. Characteristics and performance are: voltage gain/ medium; current gain/ medium; power gain/ high; input / output phase relationship/ 180 degrees; input resistance/ medium; and output resistance/ medium.
