Modulaatiomenetelmin
Modulaatiomenetelmin refers to methods of modulation, a process used in telecommunications and signal processing to encode information onto a carrier wave. The carrier wave, typically a sine wave, is altered in some way according to the information signal. This allows the information to be transmitted over a communication channel, such as radio waves or electrical cables.
There are several primary types of modulation. Amplitude modulation (AM) varies the amplitude of the carrier
Digital modulation techniques encode digital information (bits) onto a carrier. Common examples include Amplitude Shift Keying
