Pulse modulation


Board MCM30/EV studies pulse modulation transmitters and receivers: PAM (Pulse Amplitude Modulation), PWM (Pulse Width Modulation), PPM (Pulse Position Modulation), PCM (Pulse Code Modulation), PAM-TDM and PCM-TDM (Linear, Delta and Adaptive Modulation). 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.
