| 31. | It used Frequency Shift Keying ( FSK ) to send data, shifting between 20 kHz and 26 kHz.
|
| 32. | I understand the frequency shift part.
|
| 33. | The ?.5 kHz frequency shift is used along with a 25 kHz channel spacing, known as " wideband ".
|
| 34. | The combination of voltage and frequency shifts still results in a NDZ that is not considered adequate by all.
|
| 35. | The quartz crystal used as the frequency reference for the radio suffered permanent frequency shifts with each Jupiter approach.
|
| 36. | Then Maxwell's equations for original and perturbed cavities can be used to derive expressions for resulting resonant frequency shifts.
|
| 37. | These audio tones, then, SSB transmitter to produce the final audio-frequency shift keying ( AFSK ) radio frequency signal.
|
| 38. | The frequency shifts are symmetric because they correspond to the energy difference between the same upper and lower resonant states.
|
| 39. | However, turning a measures frequency shift into a force, which is necessary during a real experiment, is much more complicated.
|
| 40. | A frequency shift of the signal occurs that is caused by the movement of the satellite ( Doppler effect ).
