Hertz radio transmitter
WitrynaExtremely low frequency (ELF) is the ITU designation for electromagnetic radiation (radio waves) with frequencies from 3 to 30 Hz, and corresponding wavelengths of 100,000 … Pulsed radiofrequency is the technique whereby radio frequency (RF) oscillations are gated at a rate of pulses (cycles) per second (one cycle per second is known as a hertz (Hz)). Radio frequency energies occupy 1.0 x 10 Hz to 3.0 x 10 Hz of the electromagnetic spectrum. Radio frequency electromagnetic energy is routinely produced by RF electrical circuits connected to a transducer, usually an antenna.

In 1895, an Italian electrical engineer G Marconi developed the first radio communication system using the radio transmitter. Around 1900, radios began to be used commercially across the globe.
WitrynaA variation on the original experiments performed by Heinrich Hertz between 1886 and 1891 to transmit and detect radio frequency electromagnetic radiation. Hertz's original apparatus used a dipole E field antenna as transmitter and square loop receiver with spark gap instead of the neon bulb. Here our transmitter is a loop B field antenna.
