DEFINITION

Classification: 327/290

Having specific passive circuit element or structure (e.g., RLC circuit, etc.):

(under subclass 261) Subject matter wherein a circuit element or structure is powered only by an input signal, without any bias voltage, and produces a desired modification on the input signal without adding any amplification or gain (i.e., it presents some loss to a system).

(1) Note. Examples of passive devices are capacitors, resistors, and inductors.
