In baseband data is sent as digital single through the media as a single channel that uses the entire bandwith of the media. Baseband communication is bi-dielectional, which means that the same channel can be used to send and receive single. In baseband , frequency – division
multiplexing is not possible.
Broadband sends information in the form of an analog single. Each transmission is assigned to a portion of the bandwith. Hence multiple transmission are possible at the same time.Broadband communication is undirectional, so in order to send and recive , two pathway are needed.
Broadband can be accomplished either by assigning a frequency for sending two cables one
for sending and one for receiving. In broadband frequency division multiplexing is
