velocity filter meaning in Hindi

Examples

1. They are used to examine the direction and apparent velocity of seismic waves and in velocity filter design.
2. Therefore, Alfred Bucherer ( 1908 ) conducted a precise measurement using a velocity filter similar to Bestelmeyer's.
3. In contrast to the one dimensional output produced by multi-channel filtering, velocity filters produce a two-dimensional output.
4. A velocity filter, on the other hand, is a two-dimensional filter which produces a two-dimensional output record.
5. Velocity filters are designed to remove interfering signals by exploiting the difference between the travelling velocities of desired seismic waveform and undesired interfering signals.
6. Turbulent, or non unidirectional, air flow uses both laminar air flow hoods and nonspecific velocity filters to keep air in a cleanroom in constant motion, although not all in the same direction.
7. The radium emitted beta rays in all directions, but in any particular direction ?, only those beta rays exited the velocity filter whose speed was such that the electric and magnetic fields exactly compensated each other.
8. Using a method based on " perpendicular " magnetic and electric fields ( introduced by J . J . Thomson and further developed to a velocity filter by Wilhelm Wien ), Bestelmeyer obtained considerably different values for the charge-to-mass ratio for cathode rays up to 0.3c.
