    • An arrangement for preventing electromagnetic interference is aimed at attenuating electromagnetic emissions in electronic apparatus, especially those having a printed circuit board, a conductive enclosure, and requiring external connections to other devices. The arrangement comprises a division of the printed circuit board into two zones, a first zone having sources of unwanted electromagnetic energy, and a second zone which is electrically connected with the first zone via conductors which allows the second zone to connect to other devices. Filtering devices are incorporated into the printed circuit board and, in conjunction with integrated conducting zones, provide suitable connections to a metallic protecting enclosure in order to remove or to attenuate unwanted signal components from the signals being transmitted from the first zone to the second zone via the conductors. The protecting enclosure components enclose at least portions of the first zone of the printed circuit board for shielding direct electromagnetic emissions originating from the first zone.
    • 用于防止电磁干扰的装置旨在衰减电子设备中的电磁辐射,特别是那些具有印刷电路板,导电外壳以及需要外部连接到其他设备的电磁辐射。 该布置包括将印刷电路板划分成两个区域,具有不需要的电磁能源的第一区域,以及通过允许第二区域连接到其它设备的导体与第一区域电连接的第二区域。 过滤装置被结合到印刷电路板中,并且与集成的导电区一起提供到金属保护外壳的适当连接,以便从通过第一区传递到第二区的信号中去除或衰减不需要的信号分量 导体。 保护外壳部件包围印刷电路板的第一区域的至少一部分,用于屏蔽来自第一区域的直接电磁辐射。

    • An RF signal source having a camera that provides a camera output, an encoder that encodes the camera output in a compressed digital format, and a modulator that digitally encodes and modulates the compressed camera output and that provides the digitally encoded, modulated, and compressed camera output as an RF output of the RF signal source. The camera, the encoder, and the modulator may be contained in an enclosure. Additionally or alternatively, the encoder, the modulator, and at least part of the camera may be formed on a semiconductor substrate.
