题目内容
The Rational Unified Process (RUP) is a software engineering process, which captures many of best practices in modern software development. The notions of 3 and scenarios have been proven to be an excellent way to capture function requirements. RUP can be described in two dimensions - time and content. In the time dimension, the software lifecycle is broken into cycles. Each cycle is divided into four consecutive 4 which is concluded with a well-defined 5 and can be further broken down into 6 - a complete development loop resulting in a release of an executable product, a subset of the final product under development, which grows incrementally to become the final system. The content structure refers to the disciplines, which group 7 logically by nature. 计算机要对声音信号进行处理时，必须将它转换成为数字声音信号。最基本的声音信号数字化方法是取样一量化法。若量化后的每个声音样本用2个字节表示，则量化分辨率是______。

采用双线性变换法设计一个巴特沃斯数字高通滤波器，技术指标为：通带下限频率为fpHz，阻带上限为fsHz，通带最大衰减为αpdB，阻带最小衰减为αsdB，采样周期为T，试写出设计的具体步骤。
Networks can be interconnected by different devices. In the physical layer, networks can be connected by 20 or hubs, which just move the bits from one network to an identical network. One layer up we find bridges and switches, which operate at data link layer. They can accept 21 ,examine the MAC address, and forward the frames to a different network while doing minor protocol translation in the process. In the network layer, we have routers that can connect two networks. If two networks have 22 network layer, the router may be able to translate between the packer formats. In the transport layer we find transport gateway, which can interface between two transport connections. Finally, in the application layer, application gateways translate message 23 . As an example, gateways between Internet e-mail and X.400 e-mail must 24 the e-mail message and change various header fields.
