Goal

• The purpose of discipline is to present the principles and methods of digital signal transmission, scientific foundations and current state of digital communication networks; to give an idea of the possibilities and the natural limits of realization of digital systems of transfer and processing, to understand the patterns that define the properties of the data devices and objectives of their operation

Objective

• The technical basis of any modern communication network is information transport networks, designed for high-quality and trouble-free (uninterrupted) transmission (transportation) of information in the form of standard or normalized digital streams from producer to consumer

Learning outcome: knowledge and understanding

• The sphere of professional activity is the field of science and technology, which includes a set of technologies, means, methods and methods of human activity aimed at creating conditions for the exchange of information at a distance, the transformation of information by electronic means.

Learning outcome: applying knowledge and understanding

Assessment of the student's knowledge

Teacher oversees various tasks related to ongoing assessment and determines students' current performance twice during each academic period. Ratings 1 and 2 are formulated based on the outcomes of this ongoing assessment. The student's learning achievements are assessed using a 100-point scale, and the final grades P1 and P2 are calculated as the average of their ongoing performance evaluations. The teacher evaluates the student's work throughout the academic period in alignment with the assignment submission schedule for the discipline. The assessment system may incorporate a mix of written and oral, group and individual formats.

The evaluating policy of learning outcomes by work type

Evaluation form

The student's final grade in the course is calculated on a 100 point grading scale, it includes:

• 40% of the examination result;
• 60% of current control result.

The final grade is calculated by the formula:

 

Where Midterm 1, Midterm 2are digital equivalents of the grades of Midterm 1 and 2;

E is a digital equivalent of the exam grade.

Final alphabetical grade and its equivalent in points:

The letter grading system for students' academic achievements, corresponding to the numerical equivalent on a four-point scale:
