I'm revising attenuation and power loss logarithmic equations.
The exam formula I'm given is attenuation = 10 log (I1/I2)
I'm trying to confirm what each I stands for.
Some of the examples I'm looking at seen to give input/output power, some seem to reverse it. Which is right? What do they stand for?
