DEFINITION

Classification: 324/650

Using phasor or vector analysis:

(under subclass 649) Subject matter including utilization of a quantity that has both magnitude and direction.

(1) Note. The quantity may represent a parameter such as Z, which relates to the total opposition (i.e., resistance and reactance) a device, component or network offers to the flow of alternating current at a given frequency. Some typical parameters evaluated here are impedance, admittance or immittance. Low frequency network analyzers belong in this Subclass.

(2) Note. Complex impedance network analyzers belong in this Subclass.
