| 11. | :: : : : What you are describing is exactly the Doppler effect.
|
| 12. | Expansion is based on the assumption that the redshift is a Doppler effect.
|
| 13. | The Doppler effect was first described by Christian Doppler in 1843.
|
| 14. | For mobile applications, ATSC suffers significant signal degradation caused by the Doppler effect.
|
| 15. | It however gives a precise relative speed measurement due to the doppler effect.
|
| 16. | In either situation, calculations from the Doppler effect accurately determine the car's velocity.
|
| 17. | Transmission signal is affected by noise, interference, multipath wave propagation and Doppler effect.
|
| 18. | This will allow for, for example, realistic sound dampening, echoes and doppler effect.
|
| 19. | In military airborne applications, the Doppler effect has 2 main advantages.
|
| 20. | I am working on User : YohanN7 / Relativistic Doppler effect.
