Updated October
18, 2010
On this page we will explain
the different gain equations. We took these definitions from Noise
in Receiving Systems by Raul Pettai, an entire chapter is devoted
to this subject in this book. Thanks, again
to Jack K!
Voltage gain:

Current gain:

Note that for voltage and current
gain, the conversion to decibels is 20xlog(A). The power gains below
are converted by 10xlog(G).
Direct power gain:

Insertion gain:

Transducer gain:

Available gain:
