## ELEC 323: Signals and Systems I

### Description

Electric circuit theory and electromagnetic theory are the two fundamental theories upon which all branches of electrical engineering are built, including computer engineering. Many branches of electrical engineering such as power, electric machines, control, electronics, communications, and instrumentation, are based on electric circuit theory. Therefore, the basic electric circuit theory is "the" foundation and starting point for what follows in electrical and computer engineering programs. Circuit theory is also valuable to students specializing in other areas of the physical sciences because circuits are perfect and easy-to-understand models for the study of energy systems in general. This is also partly due to the common applied mathematics, physics, and topology involved. This course builds on fundamental physics and mathematics from APSC 112, APSC 171, APSC 172, and APSC 174.

### Course Learning Outcomes (CLOs)

• Analyse systems and determine whether they are linear, time-invariant, causal, dynamic, and stable.
• Determine the unit impulse response of an LTI system and use it to calculate the system output produced by a given input.
• Find the Fourier series of periodic signals.
• Carry out Fourier transform analysis, including filtering, and determine the frequency response.
• Use the Laplace transform to analyse continuous-time systems, including RLC circuits.
