Communication Systems

 

Communication system lab consists of various kits based on Amplitude modulation and demodulation, Frequency modulation and demodulation, Digital CROs, Function generators and power supplies. Apart from all these equipments, we work on the software of Matlab 2016b version. Experiments are conducted on kits as well as understood using software. Students write codes based on Matlab and try to simulate the results for better understanding. Kits are studied in depth and experiments are based on understanding sensitivity and selectivity of AM circuits. Variations in gain and how it can be improved using more number of IF amplifiers is understood using kits. Students also make small projects based on practicals eg, AM transmitter, AM demodulation circuit using envelope detector, FM generation circuits using varactor diode, etc.
