A-7. Inductive and capacitive.
A-11. Common collector (CC), common emitter (CE), and common base (CB).
A-12. Feedback coil. Armstrong uses a separate coil. Hartley uses a tapped coil.
A-13. In the series-fed Hartley oscillator, dc flows through the tank circuit.
A-14. Split capacitors.
A-15. Resistor-capacitor networks.
A-16. Because of the losses encountered in the RC networks.
A-20. Pulsed oscillators.
A-22. Second harmonic.
A-23. Reduce interaction between oscillator and load.
