Frequency response: Resonance, Bandwidth, Q factor
At the resonance frequency and the impedance seen by the source is purely resistive. The parallel combination of the capacitor and the inductor act as an open
Circuits in the frequency domain
Our study of capacitors and inductors has so far been in the time domain. In some contexts, like transient response, this works ne, but in many others, the time domain can be both …
