    • A high-frequency induction system can generally be achieved by detecting noise superimposed on AC power supply which might induce voltages exceeding the given break-down voltage of a switching device and in such cases by temporarily shutting off the power supply to the induction heating system. To implement this, a high-frequency induction heating system, according to the invention, is provided with a noise detector circuit connected to the output terminal of a rectifying circuit rectifying said input AC voltage. The noise detector is designed to detect noise pulses superimposed on an input AC voltage. The induction heating system of the present invention also includes means for disabling a switching device. The disabling means responds to detection of a noise pulse by the noise detector by disabling the switching device and whereby protects the circuit of the induction heating system.

    • In addition to an information signal subjected to a frequency dependent and a frequency independent loss component and delivered to an automatic equalizer through a transmission path which is typically a subscriber's communication path between a subscriber's terminal equipment and an exchange, an equalizer input signal comprises a pilot signal subjected to the frequency independent loss component alone. The equalizer comprises a first equalizer (26, 27, 36) responsive to a pilot signal component derived from the pilot signal for compensating for the frequency independent loss component. A second equalizer (31, 32, 37) compensates for the frequency dependent loss component in response to an information signal component derived from the information signal. The first and the second equalizers are cooperative in various manners in equalizing the input signal into an equalizer output signal. The pilot and the information signal components are extracted either directly or indirectly from the input signal. The output signal is fed back to a frequency dependent component detector (31) either directly or indirectly.
    • 除了受到频率依赖和频率无关损耗分量的信息信号之外,并且通过通常是用户的终端设备和交换机之间的订户的通信路径的传输路径传递给自动均衡器,均衡器输入信号包括导频 信号经受独立的频率独立损耗分量。 均衡器包括响应于从导频信号导出的导频信号分量的第一均衡器(26,27,36),用于补偿频率无关损耗分量。 第二均衡器(31,32,37)响应于从信息信号导出的信息信号分量来补偿与频率相关的损耗分量。 第一和第二均衡器以各种方式协调,以将输入信号均衡为均衡器输出信号。 导频和信息信号分量从输入信号直接或间接提取。 输出信号直接或间接地反馈到频率相关分量检测器(31)。
