“Beginning with practical difficulties in teaching communication systems in class room, this paper describes a set of innovative experimental demonstrations developed using SDR”. Communication engineering is one of the interesting, at the same time difficult subject to learn if the concept is not clear or well explained. Normal practice is that the faculties will just give a theoretical class on communication systems and for students the various communication processes like filtering, modulation, demodulation etc. are just imaginary things. Giving a clear idea about these things to a graduate and under graduate student is a little difficult task. The main aim of SDR is to create an attractive learning platform for the students where they are freed from the boring routine of theoretical learning. We are challenging current education system to think outside the “board”, where students will feel excited to learn something new so that they can physically feel and have a real time experience, which would be quite difficult to forget, for which the expense required would be quite high. So in order to better our possibilities, we suggest this software which would equip them to visualize a solid image of what they are learning about. Another fact is that as this software is so simple and is easy to learn and is feasible for everyone who would like to have basics in electronics and communication. This software is worth a stepping stone for those who would dream about being a “real” engineer. This will boost engineering students having great struggle to understand and learn communication subjects. The soul of education system should transform from “cramming as you learn” to “see as you learn’
