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 ).
