Product Details

The ESOLS Engineering product SMT-7203 Frequency Division Multiplexing (FDM) Trainer is designed to help students explore the principles of Frequency Division Multiplexing (FDM) and De-multiplexing. This technique allows multiple signals to be transmitted simultaneously over a single communication channel by assigning each signal a unique frequency band. The trainer includes two audio inputs generated through built-in audio generators, enabling users to experiment with real-time signal multiplexing. These signals are modulated using two Double Sideband (DSB) Modulators, which combine the input signals with carrier frequencies to create distinct frequency bands for transmission. On the receiving end, the De-modulator section extracts individual signals from the multiplexed transmission, demonstrating the concept of frequency separation and signal retrieval.
