摘要： In a video signal distribution system in which a plurality of video signals are modulated onto individual carrier signals spaced over a band of frequencies to form a composite signal for transmission over cables of the system, a point-to-point radio link forming part of the distribution system is provided in which the composite signal is transmitted as double side band amplitude modulation of a single microwave carrier signal.

摘要： A wide-band microwave modulator arrangement for an information transmission system, such as a video signal distribution system, in which signals from a microwave carrier signal source are split and directed over a first path comprising an attenuator and a second path comprising phase shift means and a balanced modulator, the output signals from the two paths being combined for transmission. Signals from the carrier signal source may also be directed over a third path including phase shift means and a second balanced modulator, amplified output signals from the first two paths being combined with output signals from this third path before transmission.
摘要翻译：一种用于诸如视频信号分配系统的信息传输系统的宽带微波调制器装置，其中来自微波载波信号源的信号被分离并引导到包括衰减器的第一路径和包括相移装置的第二路径，平衡调制器，来自两个路径的输出信号被组合用于传输。来自载波信号源的信号也可以被引导在包括相移装置和第二平衡调制器的第三路径上，来自前两条路径的放大的输出信号与传输之前的该第三路径的输出信号组合。
