UsageEDUCATIONAL INSTITUTES

The QPSK Modulation & Demodulation trainer is one of the advance communication trainers has an on-board Generators (8 bit selectable sequence)at 1 Kb/s is used as a Test Data source. The Even and Odd bit stream is separated from the data at half bit rate.

 

The even & odd bit combination is codified to phase modulate a carrier (100 KHz) or select one of a quadri phase modulated carriers resulting in a composite signal called Quadri Phase Shift Keying Signal. At the receiver, the instantaneous Phase of the modulated signal with respect to carrier is detected using the phase detector.

 

The four output levels corresponding to the four phase (0,90,180,270) corresponding to the 4 bit pair combinations (00,01,10,11)are used to generate the Even & Odd bit streams from which the final data is regenerated. The trainer provides complete circuit diagram, all important test points etc.
