4-channel PCM/TDM multiplexer
MCM32/EV
Board MCM32/EV studies an advanced digital communications system consisting of a 4-channel PCM multiplex. It is part of the Interactive Practical Electronics System IPES and works in both standard mode (using switches and consulting the handbook) or computerized mode. In this last case, the software version of the handbook inserts automatically circuit variations and faults, enabling the development of lessons even without teacher’s assistance. Pre-assembled electronic components divided into circuit blocks can be interconnected and modified by means of jumpers and connection cables.
