    • An apparatus and method for an analog fine delay line, a hybrid delay line, and a delay locked loop (DLL) is described. In the DLL, a coarse phase detector compares a reference signal and feedback signal in controlling coarse phase adjustment signals indicating whether a delay of a coarse delay line should be increased or decreased. Similarly, a fine phase detector compares the reference signal and feedback signal to generate a locking bias signal, which may increase or decrease a delay of an analog fine delay line. The analog fine delay line and coarse delay line may be connected in series creating the hybrid delay line having a total delay comprised of the coarse delay and the fine delay. Additionally, a fine bias generator may control the fine delay in response to an initiating bias signal from an analog phase generator or the locking bias signal.
    • 描述了用于模拟精细延迟线,混合延迟线和延迟锁定环(DLL)的装置和方法。 在DLL中,粗略相位检测器在控制粗调相位调整信号中比较参考信号和反馈信号,指示是否应该增加或减少粗延迟线的延迟。 类似地,精细相位检测器比较参考信号和反馈信号以产生锁定偏置信号,其可以增加或减少模拟精细延迟线的延迟。 模拟精细延迟线和粗延迟线可以串联连接,产生具有由粗延迟和精细延迟组成的总延迟的混合延迟线。 此外,精细偏置发生器可以响应于来自模拟相位发生器的启动偏置信号或锁定偏置信号来控制精细延迟。

    • A packed-switched facsimile network (10) and method of operation, wherein the network (10) includes a plurality of facsimile stations (12-22) and a plurality of nodes (31, 33, 35) for connecting the facsimile stations (12-22). The network (10) includes subscriber's transmission channels, such as telephone switched network (127, 29, 30), for connection to the facsimile stations (12-22), and common transmission channels, such as dedicated lines and packet switched network (36), for connection to the nodes (31, 33, 35), in order to allow the facsimile stations (12-22) to communicate with each other. In operation, the part of image data received from a plurality of facsimile stations (12-22) is formed into data packets at the nodes (31, 33, 35), simultaneously the formed data packets are sent via the common transmission channels to destination nodes, and therefrom to appropriate receiving facsimile stations. It is possible that during transmission, the destination node may transmit image data contained in one data packet, while it has not received the next data packet that contains image data to be sent subsequently, which causes transmission error. As a result, the destination node selectively inserts fill codes into image data. In the preferred embodiment, the facsimile network is a packet switching Group 3 facsimile network and the G3 machines can communicate with each other point-to-point via the packet-switched facsimile network.
    • 一种打包交换传真网络(10)和操作方法,其中网络(10)包括多个传真站(12-22)和多个节点(31,33,35),用于连接传真站(12 -22)。 网络(10)包括用于连接到传真站(12-22)的用户传输信道,诸如电话交换网络(127,29,30)以及诸如专用线路和分组交换网络(36)之类的公共传输信道 ),用于连接到节点(31,33,35),以便允许传真站(12-22)彼此通信。 在操作中,从多个传真站(12-22)接收的图像数据的一部分在节点(31,33,35)处形成数据分组,同时将形成的数据分组经由公共传输信道发送到目的地 节点,从而传送到适当的接收传真站。 可能的是,在传输期间,目的地节点可以发送包含在一个数据分组中的图像数据,同时它没有接收到包含随后要发送的图像数据的下一个数据分组,这导致传输错误。 结果,目的节点选择性地将填充代码插入到图像数据中。 在优选实施例中,传真网络是分组交换组3传真网络,并且G3机器可以经由分组交换传真网络彼此进行点对点通信。
