ADVANCED PULSE CODE DEMODULATION TRAINER


 

It has facility to demultiplexed the binary data stream and recover of the original waveform, using digital to analog conversion
Input channels : 2 numbers time division multiplexed code (de-modulated)
Receiver clock : Generated by phase lock loop (Fast mode)
Parity check facility : Even, odd, hamming, No-parity
Error Detection : Single bit error detection on LED, when even or odd parity mode is selected
Correction facility : Single bit error detection & correction, when hamming parity code is selected
Low pass filter cut-off points : 3.4KHz
LED Display : At every functional block for examination of Digital data and control signal
Interconnection : 2mm banana socket
Power Supply : +5V, +/-12V

LIST OF EXPERIMENT

  • Study of 2 channel time division demultiplexing and pulse code demodulation
  • Study of error check code logic using odd parity, even parity and hamming parity
  • Study of effect of single bit error detection i odd parity and even parity mode ad single bit error correction i hamming parity mode
  • To learn the function of phase lock loop (PLL) to a receiver clock generator and frequency syntheziser
