假设普通音频电话线路支持的频率范围为300～3300Hz，信噪比为30dB，则该线路的带宽B是（1）Hz，根据信息论原理，工作在该线路上的调制解调器最高速率V约为（2）Kbps（注：V=B*log2（（S/N）+1），S是信号强度，N是噪声强度）。 1（）
在基于构件的软件开发中， (36) 描述系统设计蓝图以保证系统提供适当的功能； (37) 用来了解系统的性能、吞吐率等非功能性属性。 （37）处填（）。
WLANs are increasingly popular because they enable cost-effective connections among people, applications and data that were not possible, or not cost-effective, in the past. For example, WLAN-based applications can enable fine-grained management of supply and distribution (1) to improve their efficiency and reduce (2) . WLANs can also enable entirely new business processes. To cite but one example, hospitals are using WLAN-enabled point-of-care applications to reduce errors and improve overall (3) care. WLAN management solutions provide a variety of other benefits can be substantial but difficult to measure. For example, they can protect corporate data by preventing (4) through rogue access points. They help control salary costs, by allowing IT staffs to manage larger networks without adding staff. And they can improve overall network management by integrating with customers’ existing systems, such as Open View and UniCenter. Fortunately, it isn’t necessary to measure these benefits to justify investing in WLAN management solutions, which can quickly pay for themselves simply by minimizing time-consuming (5) and administrative chores. 3（）
