Synchronous TDM Simulation

A sub-system based Simulink model is presented to simulate the Synchronous Time Division Multiplexing process in communication systems.

Four sine signals are time-division-multiplexed through an ideal channel. Three subsystems are present in the model:

1. MUX: Consists of a level-controlled multiport switch that passes the four signals to a Sample and Hold block to create the transmitted series of slots.

2. DEMUX: Consists of a series of switches controlled by the same level logic as the MUX block that pass each signal slot to a single wire.

3. Filtering: This subsystem is extracted from Abhilash Singh's TDM Simulink model and its function is to recover the analog signals.

*Note: MUX's signal "Sync" is the multilevel signal used for message/channel selection.
