I have a question about converting gain in an amplifier (Av, Ai, and Ap) to dB. Is there a formula used for converting. I have an example that shows Av = 1 divided by 0.01 = 100, Ai =10 divided by 1 = 10, and Ap = 100 x 10 = 1,000 then to convert amplifier gain to Decibels I have the example av = 20 log Av = 20 log 100 = 40 dB and ai = 20 log Ai = 20 log 10 = 20 dB and ap = 10 log Ap = 10 log 1000 = 30 dB. I was wondering how they get the 40dB, 20dB, and 30 dB. I have looked up about logarithms on line, but it really is not making sense to me on how they converted from Gain to Decibels. Is there a formula for this? Your help would be greatly appreciated in helping me understand the conversion process. Thank you very much for your help.
