11. The greater the frequency shift the further the distance traveled. 12. Vehicles and weather moving parallel to the radar beam produce the maximum Doppler frequency shift . 13. Where \, \ ! \ nu is the frequency shift relative to the carrier frequency. 14. The reason for the frequency shifts could be related to stress-induced physiological changes, Wilkes says. 15. Instead, a form of frequency shift keying was employed. 16. When the ring laser setup is rotating, the counterpropagating beams undergo frequency shifts in opposite directions. 17. There are many ways to get frequency shifts . 18. The moving mirror moves to shorten optical pass length, then the frequency shift toward higher frequency. 19. The test beam then passes through the Bragg cell, which adds a frequency shift f b. 20. He describes his principle that a frequency shift occurs when the source or the observer moves.
