A change in the direction of a traveling particle, usually without loss of particle kinetic energy, representing a change in velocity without a change in the scalar speed of the particle. 2. A change in the direction of a wave, beam, electron, or other entity, such as might be accomplished by an electric or magnetic field. Note: If the deflection is caused by a prism (refraction,) a mirror (reflection,) or optical grating (diffraction,) the specific applicable term should be used.
Industry:Telecommunications
A change in the value of the FM threshold of a receiver. Note: FM threshold extension may be obtained by decreasing the operational bandwidth, thus decreasing the received noise power and allowing the threshold of the desired signal to occur at a lower signal input level.
