Aims

To be introduced to practicle principles of designing electronic instruments and devices as regards both electrical and mechanical aspects - in the industrial environment.
Design and properties of signal lines, supply lines and distribution frames - suppression of interference and ground loops. Parasitic events and their suppression - coupling in input and output circuits, parasitic capacitances and inductances, thermoelectric voltage, overvoltage on inductive load, reflections on lines, crosstalk.Electric and magnetic field screening, equipotential guarding. Choice of components and application recommendation - discrete elements, operational amplifiers, comparators, electronic switches, A/D and D/A converters, sample-and-hold elements, digital circuits, microprocessors. Mechanics design: regulation, control and indication elements - lay-ou on the front panel, instrument housing design, heat removal, thermostatic elements. Printed circuits, wired printed circuits, connection of conductors and components. Safety requirements in instrument design. The student acquires concrete application knowledge of electronic instrument design, which is otherwise obtained through long-term development practice. Emphasis is laid on understanding the physical essence of parasitic events so that their knowledge can be applied to other cases. He learns to foresee and anticipate the appearance of many problems arising in the development of new instruments in both the electrical and the mechanical part of the design.
