Why the multiplexing is used

1.	Why the multiplexing is used
Answer» The very purpose of MULTIPLEXING is clearly understood in its definition only - Multiple analog signals or digital data streams are ‘combined into one signal’ over a shared medium. i.e To reduce the number of electrical connections/Wireless CHANNELS for transmission of several signals. HENCE, reducing the number of individually independent interconnections. It also simplifies the drive ELECTRONICS, reduces the cost and provides direct interface with the microprocessors. The aim is to share an expensive resource. For example: In telecommunications, several phone calls may be transferred using one wire. Else, you can imagine what would be the scenario if it wasn’t there. Another Example: Your Cable TV receives all the channels over a Single Wire only because of Multiplexing only. Else,(Without Mux) You’d need a separate wire for each Channel OR worse than that!
