    • A circuit for a front-end tunable filter of a communication and broadcast receiver and a tuning method thereof are described herein. In one aspect, the circuit of the tunable filter may be independent of the signal reception link of the receiver. The pre-filter (104) includes a variable capacitance (146) which is adjusted by a tuning signal (160). A negative resistance element (144) and the pre-filter (104) may form an oscillator. The negative resistance element (144) is controlled by an amplitude control signal (162) outputted from an oscillation amplitude control circuit (142). The oscillation amplitude control circuit (142) stabilizes the amplitude of a radio frequency signal (130) in a preset range. An oscillation frequency control circuit (140) stabilizes the frequency of the signal (130) in a preset frequency range by a tuning signal (160). The tuning is completed until both of the amplitude and the frequency of the oscillation signal meet the preset ranges.
    • 本文描述了用于通信和广播接收机的前端可调滤波器的电路及其调谐方法。 在一个方面,可调滤波器的电路可以独立于接收机的信号接收链路。 预滤波器(104)包括由调谐信号(160)调节的可变电容(146)。 负电阻元件(144)和预滤波器(104)可以形成振荡器。 负电阻元件(144)由从振荡幅度控制电路(142)输出的振幅控制信号(162)控制。 振荡幅度控制电路(142)将射频信号(130)的振幅稳定在预设范围内。 振荡频率控制电路(140)通过调谐信号(160)使信号(130)的频率在预设频率范围内稳定。 调谐完成,直到振荡信号的幅度和频率都达到预设范围。

    • A device for obtaining a RCC signal and related methods are described herein improves the reliability of the RCC signal reception and demodulation. In one aspect, a device configured to obtain a RCC signal includes: a receiving circuit to receive an analog AM RCC signal and to process said analog AM RCC signal to generate a digital AM RCC signal; and a demodulation circuit in connection with said receiving circuit, to demodulate said digital AM RCC signal to generate the RCC signal. In another aspect, a method for obtaining a RCC signal includes: processing a received analog AM RCC signal to generate a digital AM RCC signal; and demodulating said digital AM RCC signal to generate said RCC signal. Since the digital processing method is more reliable than the analog processing method, the reliability of RCC signal reception and demodulation are improved.
