Voltage Gain Calculation:
The voltage gain of an amplifier is a measure of how much the output voltage is amplified compared to the input voltage. It is usually expressed in decibels (dB). The formula to calculate voltage gain in dB is:
dB = 20 log (Vout / Vin)
where Vout is the output voltage and Vin is the input voltage.
Given Information:
In this question, we are given that the voltage gain of the amplifier is 40 dB.
Calculating Voltage Gain:
Using the formula mentioned above, we can rearrange it to calculate the output voltage in terms of the input voltage and the voltage gain in dB:
Vout = Vin * 10^(dB / 20)
Substituting the given voltage gain of 40 dB into the formula:
Vout = Vin * 10^(40 / 20)
Simplifying the expression:
Vout = Vin * 10^2
Therefore, the output voltage is 100 times the input voltage.
Identifying the Correct Answer:
The question asks for the value of AVO, which represents the voltage gain of the amplifier. From the calculation above, we can see that the voltage gain is 100, which matches with option B.
Therefore, the correct answer is option B) 100.
