Hello, up front I must state this question does relate to an assignment I am working on. I am converting gain for op amps between arithmetical and dB, and I understand the maths but I am a little confused regarding the actual notation for the two scales. If I have a gain of 20dB, is that simply G=20dB, or do I use the unit for power gain of G
P? If I use that, do I use the notation of G
V for arithmetical gain? Or, should I simply use G and the unit of dB or unit-less V/V signifies which type of gain I am talking about?
Thanks
