ANSWERS TO QUESTIONS Q1. THROUGH Q23.

A1. Sinusoidal and nonsinusoidal.
A2. RC, LC, and crystal.
A3. Relaxation oscillators.
A4. Oscillator.
A5. Amplification, regenerative feedback, and frequency-determining device.
A6. Regenerative or positive.
A7. Inductive and capacitive.
A8. Armstrong.
A9. Hartley.
A10. Colpitts.
A11. Common collector (CC), common emitter (CE), and common base (CB).
A12. Feedback coil. Armstrong uses a separate coil. Hartley uses a tapped coil.
A13. In the series-fed Hartley oscillator, dc flows through the tank circuit.
A14. Split capacitors.
A15. Resistor-capacitor networks.
A16. Because of the losses encountered in the RC networks.
A17. Four-section.
A18. Maximum.
A19. Minimum.
A20. Pulsed oscillators.
A21. Negative.
A22. Second harmonic.
A23. Reduce interaction between oscillator and load.
