Teknik Digital Modulation

Digital modulation involves mapping digital data ontero analog carrier signal. Common techques include:

  • Amplitudo Shift Keying (ASK)
  • Frekuensi Tombol Shift (FSK)
  • Phase Shift Keying (PSK)
  • Quadratule amplitudu Modulation (QAM)

Each method varieds is complexity and bandwidtch empiticiency, makindg them coparable for diferent proporctions.

Demodulation Processes

Demodulation is the of extratrting digital datta fromm recived analog signlas. Ini tidak sengaja mendeteksi transcecting in ampltude, or phase recover the reaciaI bits. Accurate demodution is crucilal for maintaing integ.
