Modulasi amplitudo nyaéta modulasi di mana sinyal (gelombang) pamawana dinyatakeun ku:
.
Amplitudo gelombang pamawa A(t) sacara liniér patali jeung informasi m(t). Modulasi amplitudo kalan-kalan disebut modulasi liniér. Gumantung kana sifat hubungan spéktral antara m(t) jeung A(t), modulasi amplitudo digolongkeun kana: modulasi pita sisi ganda atawa modulasi double-sideband (DSB), modulasi amplitudo biasa atawa ordinary amplitude modulation (AM), modulasi pita sisi tunggal atawa single-sideband (SSB), jeung modulasi pita sisi vestigial atawa vestigial-sideband modulation VSB).
- modulasi pita sisi ganda (double-sideband modulation)
- Modulasi amplitudo biasa (ordinary amplitudo modulation)
- modulasi pita sisi tunggal (single-sideband modulation)
- Modulasi pita sisi vestigial (vestigial-sideband modulation)
