以SPCE061A单片机为核心，通过DDS合成技术设计制作了一个步进值能任意调节的多功能信号源。该信号源在1KHz～10MHz范围能输出稳定可调的正弦波，并具有AM、FM、ASK和PSK等调制功能。信号输出部分采用低损耗电流反馈型宽带运放作电压放大，很好地解决了带宽和带负载能力的要求。系统带中文显示和键盘控制功能，操作简便，实现效果良好。

This article describes a sniffer for Windows. WinSniff is an application for capturing packets on the network. It displays all the packets that are transmitted on the local network and gives detailed information about each header in the packet. In order to keep it simple, I am not dealing with application level protocols. If you are interested, you can add features to support various application level protocols such as SMTP, FTP, NETBIOS etc

SDP, Service Delivery Platform, is more for telecom operators who want to manage the Data Service better delivered to the end device users by bridging with back-end content providers. Operators rely on the content provider to create & distribute data content to different types of devices. This is different from the open world in the internet communication. Operators must control who can access what content based on his rate plans. Also, based the content access results, the process will be recorded as the transaction records based on which billing statements can be generated to collected the money and shared by operators and content providers. I am working on the conceptual architecture level and the real implementation is very complicated due to too many types of service from different content providers to different types of devices based on the different types of the rate plans.
