Data conditioning and carrier modulation is done it can be demodulated and reformatted by using this trainer.
Features :
► 7 different data reconditioning formats ( NRZ ( M ), RZ, AMI, RB Biphase ( Manchester ), Biphase ( Mark ), Differentially encoded dibit to NRZ data ).
► FSK, PSK, ASK & QPSK carrier demodulation.
► Output gives 2 channels TDM multiplexed data output.
► On – board biphase clock recovery circuit.
► On – board data squaring circuit and differential decoder.
► On – board butterworth filters 4th order ( 02 nos. ).
