hi
i am interested in RF, i understand how AM circuits work, by changing the magnitude of the imput but i cant seem to find any info on how FM circuits work (if you google it you get lots of useless junk)
i mean yes i know that it varys the frequency of the wave but how?
in Am the signal is increased by adding more voltage so how in FM is the signal frequency changed?
