RFjärjestelmistä
RFjärjestelmistä refers to radio frequency systems. These systems utilize electromagnetic waves within the radio frequency spectrum to transmit information wirelessly. Radio waves are part of the electromagnetic spectrum, typically ranging from about 3 kilohertz to 300 gigahertz. RF systems are fundamental to a vast array of modern technologies.
The core principle of an RF system involves a transmitter that generates radio waves, an antenna to
Common applications of RF systems include broadcasting (radio and television), wireless communication (mobile phones, Wi-Fi, Bluetooth),
