過去十年間，許多手寫輸入的軟體平台紛紛被發展出來，但一直到最近，由於高效能理器及硬體的發展才使得桌上型大小的手寫輸入型 PC 成為主流。本書由兩方面著手，處理關於如何撰寫出色的 Tablet PC 軟體的艱鉅任務。首先，它將過去關於實用性研究的精華提煉出來，用於手寫輸入電腦，以呈現出手寫輸入使用者介面最佳化設計的官方討論。第二，利用許多的秘訣和竅門，教導程式設計者如何生產出功能最強大的應用程式，並且也為 Tablet PC Ink SDK 提供了徹底、詳盡的說明。 將過去關於實用性研究的精華提煉出來，用於手寫輸入電腦，以呈現出手寫輸入使用者介面最佳化設計的官方討論。 利用許多的秘訣和竅門，教導程式設計者如何生產出功能最強大的應用程式，並且也為 Tablet PC Ink SDK 提供了徹底、詳盡的說明。 由 Microsoft Tablet PC 開發部門對主要的軟體開發者共同撰寫。

经典天线教材。刚找到的，和大家分享~~~

The textbook consists of 13 chapters, organized as follows: & Chapter 1 introduces concepts of DSP and presents a general DSP block diagram. Application examples are included. & Chapter 2 covers the sampling theorem described in time domain and frequency domain and also covers signal reconstruction. Some practical considerations for designing analog anti-aliasing lowpass filters and antiimage lowpass filters are included. The chapter ends with a section dealing with analog-to-digital conversion (ADC) and digital-to-analog conversion (DAC), as well as signal quantization and encoding. & Chapter 3 introduces digital signals, linear time-invariant system concepts, difference equations, and digital convolutions.

产业组织理论(Industrial Organization), 研究市场在不完全竞争条件下的企业行为和市场构造，是微观经济学(个体经济学)中的一个重要分支。 产业组织理论的研究对象就是产业组织。产业组织理论主要是为了解决所谓的"马歇尔冲突"的难题，即产业内企业的规模经济效应与企业之间的竞争活力的冲突。
