- H03J 3/02 Details
- H03J 3/2 of single resonant circuit by varying inductance only or capacitance only
- H03J 3/22 of single resonant circuit by varying inductance and capacitance simultaneously
- H03J 3/24 of more than one resonant circuit simultaneously, the circuits being tuned to substantially the same frequency, e.g. for single-knob tuning
- H03J 3/28 of more than one resonant circuit simultaneously, the tuning frequencies of the circuits having a substantially constant difference throughout the tuning range
