||This course, offered in the sixth semester, introduces the fundamentals of digital communications. Building on previous courses in analog communications, the course begins with sampling and conversion to digital signals, then moves to pulse code modulation and then to digital transmission methods suitable for both sampled and data signals. Few advanced communication systems are introduced at appropriate places, as applications to the theoretical topics. This course is taught concurrently with a course in Data Communications and another in Digital Signal Processing. The three courses should provide students with a good base in modern advanced communications.
