| 1. | Hewlett-Packard's first product was an audio oscillator.
|
| 2. | Ring oscillators are built of a ring of active delay stages.
|
| 3. | The basic element for time generation is a quartz crystal oscillator.
|
| 4. | In that case, only the local oscillator frequency is changed.
|
| 5. | Too low drive level may cause problems with starting the oscillator.
|
| 6. | In 1901, Reginald Fessenden demonstrated a triode vacuum tube oscillator.
|
| 7. | They are also used in optical parametric oscillators and some interferometers.
|
| 8. | The quality factor of oscillators varies substantially from system to system.
|
| 9. | It used analog oscillators and filters alongside the existing electromechanical elements.
|
| 10. | Since each harmonic oscillator has average energy " k"
