DEFINITION

Classification: 324/615

Transfer function type characteristics:

(under subclass 612) Subject matter wherein the parameter tested is based on determining how a circuit responds to input energy at different frequencies.

(1) Note. The relationship is in general expressable as a complex entity (descriptive of multiple quantities), like a matrix, a multidimensional plot or a set of distributions for spectral variables.

(2) Note. Generalized transfer function Network Analyzers are classifiable in this subclass.
