Modulaatiokierros
Modulaatiokierros is a term used primarily in Finnish electrical and telecommunications literature to describe a modulation loop or cycle within an electronic communication system. It refers to the sequence of processes by which an input signal’s amplitude, frequency, or phase is altered to encode information, and the corresponding demodulation process that restores the original data at the receiver.
In practice, a modulaatiokierros comprises the modulator, the transmission medium, and the demodulator. The modulator converts
Historical development of modulaatiokierros techniques began with analog voice transmission in early telephone networks, evolving to
Applications of modulaatiokierros span consumer broadband, wireless cellular communications, satellite links, and industrial process control. In
