    Pulse Amplitude Modulation (PAM) employing natural sampling and flat-top PAM. Reconstruction from

    PAM and equalization. Pulse Code Modulation (PCM): Sampling, quantizing and encoding, bandwidth

    requirement of PCM, quantization noise, binary line coding.

    4.) Digital Signalling

    Line codes and their spectra, regenerative repeaters and bit synchronization. Inter-symbol Interference

    (ISI), Nyquist’s method for zero ISI and roll-off filtering. Time-division multiplexing (TDM) and TDM

    hierarchy, frame synchronization.

    5.) Bandpass Signalling Principles

    Complex envelope representation of bandpass and modulated signals, spectrum and power of bandpass

    and modulated signals.

    6.) Bandpass Signalling Circuits and Detectors

    Radio Frequency (RF) components: limiters, mixers, up and down converters, frequency multipliers, etc.

    Detector circuits: Envelope detector, product detector, frequency detector, PLL. Generalized transmitters

    and receivers: The superheterodyne principle.

    7.) AM and FM Modulated Systems

    Amplitude modulation (AM), Double-Sideband Suppressed Carrier (DSBSC) and asymmetric sideband

    signals (SSB, VSB). Phase and frequency modulated signals (FM, PM).

Laboratory/Studio Works:

    Laboratory sessions are organised in parallel to theoretical study given in classrooms. Students perform at least 8 different experiments and submit reports for evaluation

Grading Policy:

    Midterm I 20%

    Midterm II 20%

    Final Examination 35%

    Homeworks 5%

    Laboratory 20%

Makeup Exam & NG Policy:

    Only one make-up examination will be given to those who miss the midterm or the final. The student who wishes to take the make-up exam must provide a valid excuse within the next three working days. NG grade will be given to students who do not attend more than 80% of the course lecture and lab hours, and miss one exam.
