发明名称 Solid state tuner control
摘要 A television tuner arrangement is disclosed including a wide band signal selecting circuit having a solid state voltage variable capacitance selectively controllable in accordance with the level of applied voltage and a channel selector control for controlling the voltage levels applied thereto. The control illustrated herein includes a selector, actuatable to a plurality of channel selection settings, a cylindrically shaped structure providing an external surface of conductive material, and a plurality of voltage taps radially disposed about the surface of the cylindrical structural and mounted for individual movement along the conductive material. A tuning voltage bus is connected to the wide band circuit and is selectively connectable to each of the taps. The cylindrically shaped structure and the taps are mounted for rotation about the axis of the structure and ganged to the selector so that a separate tap is connected to the bus for each channel selection setting.
