Subject syllabus

Lectures:
Preparing of the development of electronic instrument. Designation of instruments (laboratory, field, mobile, and stationary). Specifications (demanded accuracy, long term stability, climatic susceptibility etc.). Electronic instruments for special environment (e.g. instruments for work in environment with intrinsic safety, etc.).
Block schematics of basic types of the electronic measurement instruments, analysis construction from viewpoint of demanded parameters. Choice signal levels, choice kind of indication of measured quantity (analog, digital) by utilization. Processing of data (storage, communication with other systems - to PC, IMS-2, telemetric transmission of data).
Analog input circuits measurement instruments. Blocks for processing direct current analog signals from of sensors. Input attenuators, input amplifiers, transducers, circuits for galvanic separation input circuits etc.
Blocks for processing alternating analog signals from sensors. Precise rectifiers. Transducers for measurement parameters alternating signals (mean and RMS value, phase shift etc.). Processing alternating signals from special sensors (e.g. strain gauges).
Continuing analyzing of problems of analog input circuits. Distorting influences of thermoelectric voltage, voltage drops on connections etc. Lf, hf, vhf signals. Leaking currents. Filtration of signal. Protection of input circuits against overloading, protection against the lightning.

Digital signal processing blocks. Choice of suitable type AD transducer. Problems of accuracy of transfer, Distortion, sources of reference voltage. Utilization on chip microcomputers.
Generators alternating signals. Oscillators, generators of shape vaweform, modulators.
Power sources of the electronic instruments. Net sources, features, problems of switched power sources. Battery sources, converters, DC-DC converters. Features of galvanic cell and accumulators.
Internally and externally, bus of the electronic instruments. Telemetric transmission of measured data.
Structure aspects of the electronic instruments. Mechanical construction, prefabricated systems, interconnection of the functional units and blocks. Problems of cooling component, influence of temperature on long-term reliability. Cases, cabinets.
Ergonomic design of instruments. MMI - locating of control knobs and displays and other MMI components, locating of connectors and terminals. Requirements on instruments for industrial utilization.
Technology of production printed circuits. Classes and accuracy. Modern design of printed circuits (examples of PCB systems). Technology of soldering, SMD. Customizing of PCB.
Materials in electronics. Special requirements on materials. Technology aspects and processes. Features of selected plastics.
