# Unit 7: Resonance and Filters

**Objectives:** Determine the resonant frequency of a series AC circuit. Evaluate electrical properties of series AC circuit at resonant and at other than resonant conditions. Determine bandwidth and quality factor of a resonant circuit. Calculate common logarithms. Use semi-log plots. Calculate gain in unit of decibels (dB). Determine the critical frequency for an RC filter. Evaluate electrical properties of RC filters below, at, and above the critical frequency. Differentiate between low and high pass RC filters.
