Multiplexing is the technique of combining multiple signals into a single signal for transmission over a communication channel. In data transmission, multiplexing allows multiple users to share a single communication channel, maximizing its use and increasing efficiency. There are several types of multiplexing used in data transmission, including: Frequency Division Multiplexing (FDM): This technique divides the available frequency range into multiple non-overlapping sub-channels, each of which can be used by a separate signal. Each signal is modulated onto a separate carrier frequency and combined into a single composite signal for transmission. FDM is commonly used in analog systems, such as radio and television broadcasting. Time Division Multiplexing (TDM): This technique divides the available time into multiple time slots, with each slot dedicated to a separate signal. Each signal is transmitted in its designated time slot, and the signals are interleaved in time to create a com
