In [[analog signal|analog]] modulation, the modulation is applied continuously in response to the analog information signal. Common analog modulation techniques include:
* [[Amplitude modulation]] (AM) (here the amplitude of the carrier signal is varied in accordance with the instantaneous amplitude of the modulating signal)<ref>{{Cite web |last=Lee |first=Sarah |title=Mastering Modulation Techniques in Wireless |url=https://www.numberanalytics.com/blog/ultimate-guide-modulation-techniques-wireless-communications |access-date=2025-07-20 |website=www.numberanalytics.com |language=en-US}}</ref>
** Double-sideband modulation (DSB)
*** Double-sideband modulation with carrier (DSB-WC) (used on the AM radio broadcasting band)
