Pulse Position Modulation .
Experimental Training Board has been designed specifically for the study of Pulse Position Modulation & Demodulation (PPM).
Using this training board one can know the specialized techniques of
Pulse Position Modulation and Demodulation. Practical experience on this
board carries great educative value for Science and Engineering
Students.
