Current Gain Formula



Current Gain
dB
=
20 *Log 10 ( Ao, Output

Ai Input)

The current output is 10 mA and the current input is 1 mA
Find the current gain, in dB. Do not use comma , to write 40,000 because you will get Not a Number NaN, error message. Enter numbers only 40000

Simply change the value of output and input for new calculation

Practice exercise:
Current Gain and Voltage Gain have the same formula Given voltage (output) signal = 40,000 Given voltage (input) signal = 1

Now calculate the voltage gain in decibels, dB. Answer is 92.041 dB


Given current gain in dB

=
20 *Log 10 ( Ao, Output

Ai Input)

The given current gain in dB is 20 and the current input is 1 mA
Find the current output in mA.

Simply change the value of given dB and input for new calculation
