As in the Gaussian system, this constant appears as the electromagnetic velocity.
3.
Coulomb's equation, used to derive the unit of charge, is in the Gaussian system, and in the HLU . The unit of charge then connects to.
4.
Both additive white Gaussian system noise \ mathbf { v } ( t ) and additive white Gaussian measurement noise \ mathbf { w } ( t ) affect the system.
5.
Adoption may have been hindered by the choice of Gaussian units, and later editions of volumes 1 and 2 were eventually published with the Gaussian system replaced by the SI.
