Summary
In this chapter, you learned about the following topics related to resonant circuits:
- How the impedance of a series LC circuit and a parallel LC circuit changes with changes in frequency.
- At resonant frequency for a parallel LC circuit, the impedance is at its highest; whereas for a series LC circuit, impedance is at its lowest.
- The concept of bandwidth enables you to easily calculate the output voltage at various frequencies and draw an accurate output curve.
- The principles of bandpass filters and notch (or band-reject) filters.
- The fundamental concepts integral to understanding how an oscillator functions.
