I realise it may be labelled as modulation levels greater than -100%,i have seen those scope pictures both there and in other places,


the point i was making was it technically only stops the carrier/modulation for a time relative too the percentage it is over -100% modulation and causes crossover distortion,it doesn't actually modulate anything.seeing as the carrier is already stopped,except for in certain cases of low level AM where it generates a dsb suppressed/reduced carrier signal,in which case it would still technically be modulating.


the term greater than -100% modulation is very misleading,its like trying to quantify something that in most cases doesn't exist.unless you classify turning the carrier off as modulation.
