Going into a SSB transmitter, the transmitter doesn’t know it is an audio tone, as all that is transmitted is the sideband of the audio modulation, or in fact, a narrow frequency modulated carrier.

It uses SDR techniques and a combination of AM and FM to achieve polar modulation and generate SSB. He’s provided a fascinating in-depth technical explanation to help understand how it works.

Single-sideband (SSB) modulation: A method whereby information is transmitted using one sideband of the carrier frequency, thereby improving spectral efficiency and reducing redundancy.

Recent innovations have integrated optical single-sideband and double-sideband modulation methods, utilising configurations such as dual-drive dual-parallel Mach-Zehnder modulators and ...
