Answer Posted / Rajat Kuamr Choudhary
Multiplexing is a technique used in telecommunications to combine multiple signals into one signal for efficient use of bandwidth. It facilitates the simultaneous transmission of multiple data streams over a single medium. There are several multiplexing categories:
1. Frequency Division Multiplexing (FDM): Allocating different frequencies to various channels within a single medium.
2. Time Division Multiplexing (TDM): Splitting the available time into fixed intervals and assigning each signal to an interval.
3. Code Division Multiplexing (CDM): Using unique codes for multiple signals, allowing them to be transmitted simultaneously over the same frequency and time slots without interference.
4. Statistical multiplexing: This is a more modern approach that dynamically allocates bandwidth based on traffic demand.
