This is clearly illustrated in a little utility I wrote which
which is here:

You can "play' with modulation percentage and carrier
level, with double or single sideband, and see what the
transmitted envelope looks like.  It is quite apparent then
why single sideband plus carrier is so awful at high
modulation percentages.
