Telecommunications Laboratory

Telecommunications Laboratory provides support to both undergraduate and graduate-level training and research. The laboratory is used in research on analog and digital communication systems. Trainings of undergraduate-level courses ELE 326 Communication Theory Laboratory I and ELE 427 Communication Theory Laboratory II are provided in the laboratory. Topics covered in this application courses are given below:

  • Fourier analysis and analog filters
  • Introduction to analog modulation methods
  • Amplitude modulation methods (Double-side band (DSB), double-side band suppressed-carrier (DSB-SC), single-side band (SSB))
  • Frequency modulation methods
  • Introduction to digital modulation methods
  • Sampling and reconstruction
  • Multiplexing methods: Time division multiplexing (TDM), frequency division multiplexing (FDM)
  • Pulse modulation methods: Pulse amplitude modulation (PAM), pulse width modulation (PWM), pulse position modulation (PPM)
  • Pulse code modulation methods: Pulse code modulation (PCM), differential pulse code modulation (DPCM), delta modulation (DM)
  • Baseband dta transmission methods: AMI, HDB3, CMI and Manchester coding
  • Shift keying methods: Amplitude shift keying (ASK), frequency shift keying (FSK), phase shift keying (PSK)
  • Effects of noise on the analog and digital communication systems
  • Practical concepts in the communication systems: Superhet receivers, stereo multiplexing, emphasis filtering, channel cross-talk, bandwidth requirements, inter-symbol interference channels, eye diagrams, data scrambling methods
