and you also get that by doubling the power 10 times (that 3 dB each time or 30
dB) and then doubling the headroom 5 times (and that is 6 dB each time, again
30 dB).

might not be so surprising for an electrical engineering grad student majoring
in signal processing or communications. �there is a class we have called
"Statistical communications", and we do random processes in that class.
