Vurderingsform
Det gis karakterene bestått/ikke bestått. Faget har en (frivillig) semesterprøve som teller i endelig vurdering dersom den teller positivt. For å ta avsluttende eksamen må man levere 5 av 6 øvinger, samt fullføre lab.
Oppsummering av pensum
- Voltage and current dividers
- Norton and Thevenin equivalents
- Impedance matching, input and output impedance
- Maximum power transfer to the load (both AC and DC cases)
- Phase shift induced by passive components
- Simple High-pass and Low-pass filters including their Bode diagrams (Both amplification and
phase)
- Resonant circuits: Give an example of a simple resonant circuit, its resonant frequency and what
the Q value is and what it means.
- Negative feedback
