The document discusses multiplexing, which is a technique to combine multiple signals into one channel. It describes multiplexing as either many to one or one to many. The chapter also covers different types of multiplexing used in telecommunications networks, such as frequency-division multiplexing and time-division multiplexing, and how signals are multiplexed and demultiplexed in both the time and frequency domains.
