Aim:
After the course the student should be able to:
- Describe principles and solve problems in connection with measurements of voltage, current, and impedance in basic circuits for data acquisition.
- Explain principles of pulse propagation, reflection and transmission on cables, with character of transmission lines, at different source resistance and loads.
- Explain the origins and reduction of electrical disturbances.
- Describe the function of data acquisition cards and describe how computers can be used to control measurements with external instruments in a LabView environment.
- Give examples on and solve problems in connection with temperature transducers and transmitters.

Prerequisites: (valid for students admitted to programmes within which the course is offered)
Be able to explain and solve problems in simple current circuits, with series and parallel connections by use of the jw-method together with Ohm�?Ts and Kirchhoff´s laws, that is, basic knowledge of electronics. Be able to exemplify and decide simple functional relationships, that is, the basic knowledges in calculus in one variable.
Note: Admission requirements for non-programme students usually also include admission requirements for the programme and threshhold requirements for progression within the programme, or corresponding.

Organisation:
The course consists of lecturers and laboratory experiments in measurement and transducer techniques.

Course contents:
Measurement of current, voltage, and impedance using multimeters and oscilloscopes. The effect of the measuring circuit at different impedance and instrument loadings. Digital oscilloscopes with applications on measurement of pulses and pulse reflections on transmission lines with different types of matchings. Frequency analysis.
Measurement and calibration of temperature transducers measured with aa DAQ card. A data acquisition card for computer-based measurement of signals is constructed and tested. The card, consisting of MUX (multiplexer), SOH (sample and hold circuit), and ADC (analog/digital converter), is measured and tested step by step during the construction. Finally, the card is connected to a computer and a simple program is written. Measurement of temperature with an IC-circuit for control of the temperature in a box. The measurement noise is reduced by a mean value process. The measurements is performed in a LabView environment. Electrical disturbances; the origin of and reducing of capacitive (electric field) and inductively coupled disturbances. Measurements and control of external measurement equipment through the computer (SCPI, USB, GPIB and others).
