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.

AM, or amplitude modulation, was the earliest way of sending voice over radio waves. That makes sense because it is easy to modulate a signal and easy to demodulate it, as well. A carbon microphone… ...

John R. Carson has been inducted into the Electronic Design Hall of Fame for his contribution to radio modulation innovations.

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

Abstract Field tests are described which investigate the transmission of compatible-single-sideband signals from a typical high-power transmitter for high-frequency broadcasting and which compare ...

This year, we recognize John R. Carson for two major contributions to communications technology: the invention of single-sideband (SSB) modulation and his rule for estimating ...
