MSK Modulation / Demodulation Trainer is designed to assist students to understand the basic working principal of Minimum Shift keying technique. As the name suggests, MSK results in a modulation scheme which has smooth phase variations in contrast to other phase modulation schemes where the modulated signal contains abrupt phase changes. The immediate advantage of such a scheme is the reduction in modulated signal bandwidth. MSK Modulation / Demodulation comprises of following major blocks :
– Digital data generator
– Sine and Cosine wave generator for wave shaping
– Sine and Cosine carrier generator
– Clock signal generator
– MSK modulator and Demodulator sections with complete signal flow
