Calculating total gain.

[early]

Is it as simply as adding to gain values together, ie 20db + 40db = 60db.

Or is it non linear, in which case how do you do it?.

Totally as simple as adding them up

This is the simplicity for using logarithms. To multiply you just add the logs together.

However this doesn't necessarily mean in practice that it is all usable and you don't mix Voltage and power gains.
