Voltage Gain
dB | = |
20 *Log 10 (
Ao, Output
Ai
Input)
|
The voltage output is 9.976 V and the voltage input is 5 V
Find the Voltage gain, A , in dB.
Simply change the value of output and input for new calculation. Do not enter comma , for example 40,000 because you will get a NaN error message, meaning Not a Number because of the comma sign ,
| Practice exercise: | |||
Now calculate the voltage gain in decibels, dB. Answer 92.041 |
|
Given voltage gain in dB
| = |
20 *Log 10 (
Ao, Output
Ai
Input)
|
The given voltage gain in dB is 6 and the voltage input is 5 V
Find the Voltage output in V.
Simply change the value of given dB and input for new calculation
Another example: An amplifier has input of 2 mV rms and output of 400 mV rms. Calculate the voltage gain in dB.
