After studying the material in this chapter, you should be able to: - State the function of the oscillator.
- Describe positive feedback, how it is produced, and how it maintains oscillations after an oscillator is triggered.
- Discuss the Barkhausen criterion and its effect on oscillator operation.
- List the three requirements for proper oscillator operation.
- Describe the operating characteristics of the phase-shift and Wien-bridge RC oscillators.
- Describe the operation and perform the complete frequency analysis of a Colpitts oscillator.
- Describe the operation of the Hartley, Clapp, and Armstrong LC oscillators.
- Describe the operating principles of crystals and crystal-controlled oscillators.
- Describe the overall approach to (and difficulties involved in) oscillator troubleshooting.
