  9.    Course Prerequisites
10. Course Goals (acquired competencies):  The student will acquire fundamental knowledge of the field of digital communications, such as various techniques of conversion of analog signals to digital signals, various types of digital modulation techniques, the optimum receiver and the optimum detector of digital signals and detection error probability, and transmission of digital signals through band-limited systems and equalization techniques. The acquired knowledge is the basis for understanding the modern digital transmission systems, and a prerequisite for other subjects with more specific content.
11.    Course Syllabus: Sampling Theorem. Pulse Code Modulation. Uniform Quantization. Optimal Scalar Quantization. Non-uniform Quantization. Vector Quantization. Diferential Pulse Code Modulation. Delta Modulation. Linear Predictive Coding and Application to Speech Coding. JPEG Image Coding. Representation of Signals in Signal Space: One-dimensional, Two-dimensional, Multi-dimensional Signals. Optimal Receiver for Digitally Modulated Signals in the Presence of Additive White Gaussian Noise. Optimal Detector. Detection Error Probability in the Presence of Additive White Gaussian Noise: PAM, QAM, PSK, orthogonal signals. Spread spectrum signals. Transmission of Digital Signals through Band-Limited Channels. Signal Design for Transmission through Band-limited Channels. Equalization. Linear Equalizers. OFDM.

19.    Conditions for acquiring teacher’s signature and for taking final exam Attending the Lectures, Recitations and Laboratory Excersises.
20.  Forms of assessment During the semester, two partial written exams are conducted (at the middle and at the end of the semester, duration 120 minutes), tests that are conducted during the classes and a test covering the laboratory exercises. For students who have passed the partial exams and the laboratory exercise test, a final oral exam (of duration 60 minutes) may be administered. The final grade includes points from the partial exams, tests and the final oral exam.
In the planned exam sessions, a written exam is taken (duration 120 minutes). For students who have passed the written exam and the laboratory exercise test, a final oral exam (duration 60 minutes) may be administered. The final grade includes points from the written exam, tests and the final oral exam.
The student should prepare a seminar paper and submit it by the exam date at the latest. It is not allowed to use books, lecture notes, written material and notes of any kind during the exam, as well as a mobile phone, tablet or any other electronic device, except a calculator
