It is not possible to register for the course B2B38EMB if the student is concurrently registered for or has already completed the course A2B38EMB (mutually exclusive courses).

During a review of study plans, the course A2B38EMB can be substituted for the course B2B38EMB.

In order to register for the course B2B38EMB, the student must have registered for the required number of courses in the group BEZBM no later than in the same semester.

It is not possible to register for the course B2B38EMB if the student is concurrently registered for or has previously completed the course A2B38EMB (mutually exclusive courses).

The requirement for course B2B38EMB can be fulfilled by substitution with the course A2B38EMB.

Synopsis:

Methods of measurement of electrical quantities (voltage, current, power, frequency, resistance, capacitance, and inductance) are explained together with principles of their correct application and accuracy estimation. The course is closed by presenting information on several basic electronic measuring instruments and explaining the fundamentals of magnetic measurements and basic information concerning measurement systems.

Syllabus of lectures:

1. Introduction - measuring chain, the accuracy of measurement - evaluation of uncertainties of direct and indirect measurements, the error of method and its correction.

2. Instruments for voltage and current measurement.

3. Measuring amplifiers with OA, converters of average and of RMS value, phase-sensitive rectifier.

4. Converters for sum and difference measurement, analog multipliers, measurement of frequency and phase shift.

5. AC or DC current and voltage measurement - standards, methods, and instruments

6. Principle of sampling and quantization of analog signal, DACs, and ADCs - principle, and properties.

7. Measurement of resistance - converter R - U; methods for low and high resistance measurement, unbalanced Wheatstone bridge for sensor application.

8. Present-day digital multimeters, common mode rejection, the principle of autocalibration and software calibration.
