... This logic output goes high when negative power is detected, that is, when the phase angle between the voltage and current signals is greater than 90°. This output is not latched and is reset when positive power is once again detected. The output goes high or low at the same time that a pulse is iss ...

... case are just the principal ideals. We state these facts in the form of a theorem. Theorem 3. The family of all closed subalgebras of an algebra with topology is lattice isomorphic to a complete lattice which is a family of ideals of a semilattice. The semilattice may be taken to be the family of al ...

Mathematics of radio engineering
The mathematics of radio engineering is the mathematical description by complex analysis of the electromagnetic theory applied to radio. Waves have been studied since ancient times and many different techniques have developed of which the most useful idea is the superposition principle which apply to radio waves. The Huygen's principle, which says that each wavefront creates an infinite number of new wavefronts that can be added, is the base for this analysis.
