    摘要： A linear tuning varactor circuit has the first single-end varactor circuit, the second single-end varactor circuit and a voltage divider. The first single-end varactor circuit has tuning terminal receiving the tuning voltage to change the capacitance thereof The second single-end varactor circuit has a reference voltage terminal receiving the reference with constant voltage. The first single-end varactor circuit and the second single-end varactor circuit are coupled to each other in series and have a node. The voltage divider is coupled to the tuning terminal, the reference voltage terminal and the node. The node has a divided voltage, which results from dividing a voltage difference between the tuning voltage and the reference voltage by the voltage divider with a pre-set voltage dividing ratio.

    摘要： A standardized tuning structure is disclosed which is capable of being digitally tuned to correspond to selected communication channels, the standardized construction being adaptable for use in connection with whatever communication channels, in whatever band range, may be present in a given locality. Thus while there may be some eighty or more available channels, with only a small number of them available in a given locality, the standardized matrix-type tuning system can be used in any locality simply by making appropriate electrical connections to a terminal board. All-electrical circuitry is provided to effect the desired tuning and band selection, that circuitry including a novel pulseproducing circuit specially adapted to cooperate with touch-type switches, and also including flip-flop circuits and AND-gates for controlling band and channel selection and appropriate tuning within the communication receiver.

    摘要： A receiver tuning circuit in which without operation of extra switches a change-over can be made from tuning by means of a continuously varying tuning voltage to tuning by means of one of a number of adjusted tuning voltages by using a capacitor controlled by an automatic tuning correction current source circuit for obtaining said voltage, and an automatic switch for applying the desired tuning voltages to this capacitor.
