DEFINITION
Classification: 324/76.51
By tuning (e.g., to resonance, etc.):
(under subclass 76.39) Subject matter having circuit which may be adjusted for resonance at a particular frequency or other predetermined condition.

76.41+, for this subject matter in combination with heterodyning means.
76.49+, for this subject matter where the tuned current has a tuned mechanically resonant element.

250, for this subject matter in combination with a radio or carrier wave communication frequency
334, Tuners, appropriate subclasses for tuned networks for use in wave energy apparatus and comprising inductance and capacitance elements in circuit arrangement to form a resonant circuit and in which structure is provided for adjusting one or both of these elements for changing the mean resonant frequency of the circuit. 455, Telecommunications,
154.1+, for indicator means combined with frequency selection means in a radio receiver.
