| 41. | The only difference between each of these lines is the doppler shift that each of these lines has.
|
| 42. | These widths are due to Doppler shifts caused by the high speeds of the gas emitting the lines.
|
| 43. | Frequency offsets are typically caused by mismatched transmitter and receiver oscillators, or by Doppler shift due to movement.
|
| 44. | The received signal was retransmitted to the ground, where its Doppler shift was examined to extract the range information.
|
| 45. | Spectroscopic binaries can be found by observing doppler shifts in the spectrum of the star and its close companion.
|
| 46. | Meteor radars can measure atmospheric density and winds by measuring the decay rate and Doppler shift of a meteor trail.
|
| 47. | Phase coherent signals also allowed for the direct measurement of velocity via the Doppler shift of a single received signal.
|
| 48. | He attempted to measure their velocity by the Doppler shift of spectral lines in the glow emitted by Crookes tubes.
|
| 49. | It is easy to recognise a doppler shift in CF calls of flying bats due to their speed of flight.
|
| 50. | An important feature of META was its use of frequency Doppler shift to distinguish between signals of terrestrial and extraterrestrial origin.
