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 ...

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 ...

The range of this FM transmitter is around 100 meters at 9V DC supply. The circuit comprises three stages. The first stage is a microphone preamplifier built around BC548 transistor. The next stage is ...

The circuit is a simple VHF FM transmitter circuit. It is basically a VHF Colpitts oscillator capable of transmitting sound or music to any standard FM receiver/FM Transmitter. The circuit is a simple ...

Smallest FM radio transmitter just created using graphene by the wizards at Columbia University. This one is pretty cool and I certainly do not want to butcher the idea and explanation behind it all.

The heart of every radio transmitter is a reliable oscillator. Creating small, and tunable, oscillators that can maintain a precise frequency when conditions like temperature, pressure or humidity ...
