摘要： Conversion of an RF signal amplifier from an unbalanced signal configuration to a balanced signal configuration is provided while including an image trap for both sides of the balanced circuit. The grounded side of the secondary of a double tuned circuit (14,16,18,20,22) is lifted from ground to provide a balanced circuit configuration. A trap filter is provided in the balanced circuit configuration by a pair of small capacitors (CS1,CS2) coupled between the balanced secondary leads (26a,26b) to appropriate signal nodes.
摘要翻译：提供RF信号放大器从不平衡信号配置到平衡信号配置的转换，同时包括平衡电路两侧的图像陷波器。双调谐电路（14,16,18,20,22）的次级的接地侧从地面提升以提供平衡电路配置。通过耦合在平衡的次级引线（26a，26b）之间的一对小电容器（CS1，CS2）到适当的信号节点，在平衡电路配置中提供陷波滤波器。

摘要： A television receiver includes a single tuner for tuning both television channels and broadcast FM stations. The tuner (102) serves as the first conversion stage of a double conversion FM receiver, wherein the mixer (180b) of an FM radio integrated circuit (180) serves as the second conversion stage. The receiver provides an on-screen display (410) of the currently tuned FM channel number. Circuitry (110,105,Q,Q2) is provided for interrupting the path of signals from the tuner to the IF amplifier stage of the television receiver when the receiver is in FM radio signal reception mode, to prevent the FM radio signals from adversely affecting the television synchronizing signals during the display of the FM channel number.

摘要： 5 A television receiver includes a single tuner (102) for tuning both television channels and broadcast FM stations. The tuner (102) is operated at a fixed gain setting in FM reception mode. The tuner (102) serves as the first conversion stage of a double conversion FM receiver, wherein the mixer (180) of an FM radio integrated circuit serves as the second conversion stage. The arrangement operates at a specific and non-arbitrary first IF frequency. The FM receiver is also capable of automatically receiving National Weather Service broadcasts on that one of NWS's seven allocated frequencies which is operating in a listener's area. The receiver provides an on-screen display of the currently tuned FM channel number.
