Answer:
A multiplexer divides one high-speed communication circuit into several lower speed circuits for the primary reason of saving communication line costs.
Explanation:
- The operation carried out using a single high-speed communication circuit costs way more than the operation carried out using multiple lower speed circuits.
- The multiplexer enables the breaking of the circuit efficiently in order to split the signals to travel through multiple lower speed circuits.
- Though the use of a multiplexer reduces the efficiency of the operation, it also helps in cutting the operation costs substantially.
