Digital Control of Telecommunications Systems

The course is a substitute for:

Digital Control of Telecommunications Systems (32CRT)

Lecturer:

Tutor:

Supervisor:

Department of Telecommunications Engineering

Synopsis:

Subject CRT deals with basic principles of digital logic circuit solutions used in control of digital telecommunications systems. Uses basic view of sequential logic circuit, focuses at its synthesis, clarifies individual steps of synthesis. Deals also with properties and process of synthesis of special sequential circuits, i.e. receivers of ac code, memory elements, counters, registers, shift registers and microprogammable machines and their synthesis.
