Teaching the digital transmission techniques- like other fields of electronic- is not always easy : There is classically theoretical courses and practical lessons. The link between the two is often the most important difficulty that appears for the students. An abundant literature on digital wireless with a high level mathematical of modelling is of course available. Since a few years, theoretical courses are easily illustrated by the 2D computer simulations. But simple descriptions or analysis are rarely found and simulations do not replace a concrete true design. In order to improve the efficiency of our teaching, we present here a practical and pedagogical low cost BPSK modulator/demodulator model kit to teach modulation during practical lessons.
