modulationssystemer
Modulationssystemer refer to the methods used to encode information onto a carrier signal for transmission. This process is fundamental to all forms of wireless communication, from radio broadcasting to mobile telephony and satellite systems. The core idea is to alter some property of the carrier wave, such as its amplitude, frequency, or phase, in accordance with the information being sent.
Amplitude Modulation (AM) is one of the simplest forms, where the amplitude of the carrier wave is
Digital communication systems employ digital modulation schemes. These involve mapping digital data bits to specific states
The choice of modulation system depends on various factors, including the available bandwidth, the desired data
