One of our favorite purveyors of electronics knowledge is at it again. This time, [Afroman] explains how frequency modulation works while building up a short-range FM transmitter on a board he has ...
Placing a sheet of atom-thin graphene into a feedback circuit causes spontaneous self-oscillation that can be tuned to create frequency-modulated (FM) signals. Changyao Chen, Sunwoo Lee, Columbia ...
Scientists have taken advantage of graphene's special properties -- its mechanical strength and electrical conduction -- and created a nano-mechanical system that can create FM signals, in effect the ...
