Courses taught

Course Objectives

Students acquire essential knowledge of principles and properties of basic digital circuits. Gain practical experience to design and construct digital electronic devices and programing selected microprocessors and simple robotic systems.

Syllabus
Principles of DDL, DTL and TTL circuits,
Boolean functions – combinational logic networks and their optimization,
– some combination circuits (adder, multiplexer and demultiplexer)
Physical implementation of automata (sequential circuits and their applications)
– RS and D flip-flops,
(counter, shift register, three-state output, memory management (R/W))
– parallel to serial code converter and RS232 interface,
– static and dynamic RAM memories and their organization
Microprocessors.
Microprocessor structure
Arithmetic Logic Unit (ALU) Structure
Implementation of instructions and their distribution
Addressing methods,… internal and external memory
Additional devices – their connection and data transfer (data transfer, bus)
Realization of binding circuits (interface) for memories and peripheral devices
Characteristics affecting the performance of computers (clock frequency, access time, transfer capacity, size of registers…)
Programming of single-chip microcomputers in a high- and low-level programming language and the basics of robotics, types of signals, their processing and control.
Course Objectives

Acquisition of skills in registration and data processing by computer, measurement of electrical and magnetic quantities. Physical interpretation and written / graphic presentation of processed results.

Syllabus

In the initial two or three exercises, joint acquisition of skills and measurement with analog and digital devices (oscilloscope, digital multimeter, A / D converter), processing of measured data by computer. This is followed by five to six separate laboratory works on electricity and magnetism selected from the offer: electrical properties of substances – electric bridges, Hall effect; electric field mapping; magnetic field mapping – air coils; electromagnetic induction – transformer; electrical RLC oscillations – transient RLC phenomenon, serial and parallel RLC circuit; magnetic properties of substances – hysteresis loops, permeability of substances, separation of magnetic losses; fuel cell; determination of the specific charge of an electron (e / m0).
