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 .
