| 1. | The finesse of the cavity and the modulation frequency.
|
| 2. | In the case of nonlinear systems, higher harmonics of the modulation frequency appear.
|
| 3. | Within the STIPA signal, each octave band is modulated simultaneously with two modulation frequencies.
|
| 4. | This effectively makes the system AM at low modulation frequencies and SSB at high modulation frequencies.
|
| 5. | This effectively makes the system AM at low modulation frequencies and SSB at high modulation frequencies.
|
| 6. | Harmonic spectrum in the output depends on the width of the pulses and the modulation frequency.
|
| 7. | Another important factor is the modulation frequencies which should be close to the actual missile frequencies.
|
| 8. | If the modulation frequency is too high the two " dips " in the curve increase.
|
| 9. | A lock-in amplifier is then used to measure deflections found at the modulation frequency.
|
| 10. | Fender replaced them with neon lamps, which increased the modulation frequency and reduced the controlling currents.
