| 11. | If the frequency deviation is held constant and the modulation frequency increased, the spacing between spectra increases.
|
| 12. | AM broadcasting uses a channel spacing of 10 kHz, but with amplitude modulation frequency deviation is irrelevant.
|
| 13. | It is also responsive to specific amplitude modulation frequencies and this might be responsible for detection of pitch.
|
| 14. | In practice, the modulation frequency is chosen slightly higher than the bandwidth of the STM feedback system.
|
| 15. | The STIPA signal contains such intensity modulations at 14 different modulation frequencies, spread across 7 octave bands.
|
| 16. | Beyond multi-sensory integration IC responds to specific amplitude modulation frequencies, allowing for the detection of pitch.
|
| 17. | However, thermal effects practically limit the modulation frequency to around 20 GHz, making this approach is inefficient.
|
| 18. | Such effects arise from the capacitance between the tip and the sample, which grows as the modulation frequency increases.
|
| 19. | The thermal diffusion length ( the distance the heat spreads ) is inversely proportional to the root of the modulation frequency.
|
| 20. | If there is a ?A, then a small AC voltage will be present that corresponds to the modulation frequency, ?.
