Homework Help: Attenuation and power loss

  1. Mar 25, 2014 #1
    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?
