Single-Course Danish 5 ECTS

Electric circuits 1

Overall Course Objectives

To train skills in analyzing and synthesizing simple electronic circuits for processing of analog signals.

Learning Objectives

  • Define current, voltage, and power. Explain independent and dependent ideal voltage and current sources.
  • State and apply basic circuit laws (Kirchhoff) and solve circuits by systematic node-voltage and mesh-current techniques.
  • Solve simple circuits with resistances in series or parallel. Apply relaations for voltage dividers and current dividers.
  • Find and apply Thévenin and Norton equivalents. Apply the superposition principle.
  • Explain and apply component relations for capacitances and inductances. Find DC-solutions for circuits with resistances, capacitances and inductances. Solve first-order RC and RL transient problems.
  • Explain and use generel amplifier models and amplifier concepts.
  • Explain the ideal opamp and comparator. Analyze ideal opamp circuits with negative feedback. Explain and analyze standard opamp circuits, such as voltage follower, inverting and noninverting voltage amplifier, integrator, and differentiator. Analyze ideal comparator circuits.
  • Explain diode models and use the ideal-diode model and piecewise-linear models to solve circuits. Explain various rectifier circuits and complete rectifier systems.
  • Explain the operation of transistors (bipolar and/or FET). Use large-signal equivalent circuits to analyze transistor circuits. Use small-signal equivalent circuits to analyze transistor circuits.
  • Make computer simulations of simple circuits by the use of simulation programs (currently LTspice).
  • Make laboratory measurements with standard laboratory equipment.
  • Understand Danish and English basic electro-technical terminology.
