This certainly does seem to reinforce the idea that the carri; /rsgb_lf_group-archives/html/rsgb_lf_group/2002-07/msg00002.html (9,355 bytes)

Modern broadcast transmitters can be set to reduce the carrier when there is no mod, to save power, or raise the carrier to preserve a silent background in the face of interference.

To start with, one takes a carrier or some power, then one modulates its amplitude. This process spreads some of the energy into the symetrical; /rsgb_lf_group-archives/html/rsgb_lf_group/2002-08/msg00209.html (9,230 bytes)
