    • Deterioration of television reception sensitivity is prevented by using a noise signal generated from a noise signal source in a portable device. A first case includes a first coupling element connected to one of input parts of the noise-cancelling section in a part of a facing surface thereof. A second case includes a second coupling element supplied with a noise signal from the noise signal source in a part of a facing surface thereof. When the television signal is received with the noise signal source brought in a vicinity of the television receiving antenna, the first and second coupling elements are brought in a vicinity of each other and coupled at a high frequency so as to form a noise signal transmission section. The noise-cancelling section noise-cancels the first noise signal by a second noise signal transmitted to the noise-cancelling section via the noise signal transmission section.
    • 通过使用从便携式设备中的噪声信号源产生的噪声信号来防止电视接收灵敏度的恶化。 第一壳体包括在其面对表面的一部分中连接到噪声消除部分的输入部分中的一个的第一耦合元件。 第二种情况包括在其面对表面的一部分中从噪声信号源提供有噪声信号的第二耦合元件。 当利用带在电视接收天线附近的噪声信号源接收电视信号时,第一和第二耦合元件彼此附近并以高频耦合,以形成噪声信号发送部分 。 噪声消除部通过经由噪声信号发送部分发送到噪声消除部分的第二噪声信号来噪声消除第一噪声信号。

    • A noise canceller includes an input terminal for receiving an input signal containing a received signal and a first noise signal generated by a noise source, a first delay unit for delaying the input signal, a pick-up antenna for receiving a second noise signal generated by the noise source, a cancel-signal generator for generating a noise-canceling signal based on the second noise signal, and a combiner for combining the delayed input signal and the noise-canceling signal so as to cancel the first noise signal contained in the input signal, and outputting the received signal. The noise canceller can include a second delay unit for delaying the second signal instead of the first delay unit or in addition to the first delay unit. This noise canceller cancels the noise signal generated by the noise source, thereby providing an electronic device having a preferable receiving sensitivity.
    • 噪声消除器包括用于接收包含接收信号的输入信号和由噪声源产生的第一噪声信号的输入端,用于延迟输入信号的第一延迟单元,用于接收由第二噪声信号产生的第二噪声信号的拾取天线 噪声源,用于基于第二噪声信号产生噪声消除信号的消除信号发生器,以及用于组合延迟输入信号和噪声消除信号的组合器,以消除输入中包含的第一噪声信号 信号,并输出接收到的信号。 噪声消除器可以包括第二延迟单元,用于延迟第二信号而不是第一延迟单元,或者除了第一延迟单元之外。 该噪声消除器消除由噪声源产生的噪声信号,从而提供具有优选的接收灵敏度的电子设备。
