Analog Modulation

Analog Modulation


Dalam modulasi analog, proses modulasi merupakan respon atas informasi sinyal analog.
Teknik umum yang dipakai dalam modulasi analog adalah:

  • Modulasi Amplitudo (Amplitude Modulation - AM)
    • Double-sideband modulation with unsuppressed carrier (used on the radio AM band)
    • Double-sideband suppressed-carrier transmission (DSB-SC)
    • Double-sideband reduced carrier transmission (DSB-RC)
    • Single-sideband modulation (SSB, or SSB-AM), very similar to single-sideband suppressed carrier modulation (SSB-SC)
    • Vestigial-sideband modulation (VSB, or VSB-AM)
    • Quadrature amplitude modulation (QAM)
  • Angle Modulation
    • Modulasi Fase (Phase Modulation - PM)
    • Modulasi Frekuensi (Frequency Modulation - FM)
 
Sinyal informasi frekuensi rendah dibawa oleh 
gelombang radio dengan modulasi AM dan FM
