Definitions for "Velocity of Propagation"
The ratio of the speed of a radio frequency wave within a cable or dielectric as compared with the same wave in free space.
The transmission speed of electrical energy in a length of cable compared to speed in free space. Usually expressed as a percentage. Test devices use velocity of propagation to measure a signal's transit time and thereby calculate the cable's length.
Velocity at which a wave propagates. Units are meters per second (m/s). It is equal to how far one point on the wave, such as the crest or trough, travels in 1s.
