1/2 power for AM plus 1/2 power for PN plus another 1/2 to convert from DSB to
SSB.

HI,
How is that calculated? I only get this far:
9.6nV/sqrt(Hz) into a 50R load is 1.8e-18 W/Hz or -147.3 dBm/Hz
what then? split half-and-half into AM and PN, and how to relate that to
the carrier power +10dBm?
thanks,
Anders
