For single subject courses within Chalmers programmes the same eligibility requirements apply, as to the programme(s) that the course is part of.


The course will give the basic methods for analysis of and measurements on electrical circuits and systems.


Part A: The course will be started will a survey of the risks at work on electrical circuits. Safety regulations and instructions concerning measures to be taken at accidents will be given.
One port networks. Current, voltage, power. Linear circuit elements. Kirchhoff's laws. Analysis of linear direct current circuits. Superposition. Thevenin and Norton equivalent circuits. Operational amplifiers.
Capacitance. Inductance. Charging and discharging phenomena. Differential equations. Transient och steady-state response. Phasors. Impedance and admittance.
Alternating current circuits. Resonant circuits. Network functions. Bode diagrams. Average, reactive and complex power. Maximum power transfer. Ideal transformers.
Electrical measurements. Analogue and digital measuring instruments. The oscilloscope. Measurement accuracy. Use of MATLAB for solving matrix equations.

Part B: CONTINOUS TIME SIGNALS AND SYSTEMS. Different classes of signals, periodic and aperiodic signals. Convolution and correlation. Fourier series and Fourier transforms. Parseval's relation. Power and energy spectrum. Time-invariant systems. The Laplace transform. Alternative ways to caracterize dynamic systems: the transfer function, frequency response, the impulse response, poles and zeroes, differential equations. Filter characteristics: low-pass, high-pass, band-pass and band-reject filters. Filter specifications. DISCRETE TIME SIGNALS AND SYSTEMS: Sampling, aliasing. The discrete Fourier transform and the Fast Fourier transform. The z-transform. Alternative ways to characterize dicrete systems: the transfer function, frequency response and difference equations.


Part A: Lectures, exercises, compulsory laboratory work, compulsory assignment.

Part B: Class lectures, exercises, computer lab. Computer exercises (optional). Home work assignments (optional).
