In analog modulation, the modulation is applied continuously in response to the analog information signal.

Common analog modulation techniques are:

  • Amplitude modulation (AM) (here the amplitude of the modulated signal is varied)
    • Double-sideband modulation (DSB)
      • Double-sideband modulation with unsuppressed carrier (DSB-WC) (used on the AM radio broadcasting band)
      • Double-sideband suppressed-carrier transmission (DSB-SC)
      • Double-sideband reduced carrier transmission (DSB-RC)
    • Single-sideband modulation (SSB, or SSB-AM),
      • SSB with carrier (SSB-WC)
      • SSB suppressed carrier modulation (SSB-SC)
    • Vestigial sideband modulation (VSB, or VSB-AM)
    • Quadrature amplitude modulation (QAM)
  • Angle modulation
    • Frequency modulation (FM) (here the frequency of the modulated signal is varied)
    • Phase modulation (PM) (here the phase shift of the modulated signal is varied)
