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 ...
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 ...
A group of mechanical engineers at Columbia University have produced the world’s tiniest FM radio transmitter. At its heart is a micrometer-sized oscillator powered by one-atom-thick graphene. But ...
Recent statistics show that not everybody uses Android Auto and CarPlay when driving, even if their cars come with such capabilities. A significant share of drivers still listen to radio stations, as ...
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 ...
Ever since a young Henrich Hertz began constructing the scores of electrochemical cells needed to power the world’s first radio transmitter in the 1880s, designers have sought out better and more ...
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 ...
The Si47xx series of integrated circuits from Silicon Labs is a fascinating series of consumer broadcast radio products, chips that apply SDR technologies to deliver a range of functions that were ...
