Mulitiplexer by the very name, suggests more than one signal is transmitted through the same fiber optic cable. This trainer helps to view how signals from different signal sources are multiplexed and transmitted. This trainer has 16 channel Mulitiplexer. 16 independent external signals from external source can be applied as input to this data Mulitiplexer. The necessary timing generator and sync signal generator are included on board. This is used as synchronizing signal for the receiver for decoding purpose. In order to demonstrate this principle, 3 different signals are generated onboard, namely a pseudo-random bit sequence (PRBS) generator, a pulse and SINE generator of 1 kHz. Using these three signals, the user can start study of Mulitiplexer and De-Mulitiplexer. An external dual beam oscilloscope is required for observing the input and output signals. For ease of study, both transmitter and receiver are assembled on the same board. Specification:
