Subcarrier - Wikipedia
WEBA subcarrier is a sideband of a radio frequency carrier wave, which is modulated to send additional information. Examples include the provision of colour in a black and white television system or the provision of stereo in a monophonic radio broadcast.
What is a Subcarrier Signal? Definition from SearchNetworking
WEBWhat is a subcarrier? A subcarrier is a secondary modulated signal frequency modulated into the main frequency (the carrier) to provide an additional channel of transmission. It allows for a single transmission to carry more than one separate signal.
