DEFINITION

Classification: 324/612

Parameter related to the reproduction or fidelity of a signal affected by a circuit under test:

(under subclass 600) Subject matter wherein the parameter relates to the accuracy with which a circuit reproduces at its output the essential characteristics of a signal impressed on its input.

(1) Note. Some instances of parameters relating to signal reproduction or fidelity are: (a) a transfer function characterizing a circuital behavior; (b) the desired or undesired noise characteristics of a network; (c) the effects of poor common mode rejection; (d) the distortion of any type induced by a network; (e) tuning characteristics, etc.
