SignalsLaajuus (3 ECTS)

Objective

After completion of the course the student understands the frequency domain representation of signals and can use tools (Fourier-transform, LaPlace-transform) to analyze circuits. Also the transients in reactive circuits can be analyzed.

The student understands the concept of mutual inductance and can analyze simple transformer circuits. Harmonic analysis will be studied and the student can use this method to analyze multifrequency signals in circuits. Transfer function and resonance phenomenon are also discussed.
