用LPC213X系列的PWM來產(chǎn)生語音。語音數(shù)據(jù)來源于PC機(jī)轉(zhuǎn)換后得到的。最大可以是16位的。
由于是PWM所以輸出端口需要低通濾波才能夠得到比較干凈的聲音。
可以經(jīng)過修改使用LPC2132以上的ARM的D/A來產(chǎn)生。
This project outputs audio on PWM0 using wave samples that are stored in the on-chip Flash ROM.

The SharePoint Products and Technologies 2003 Software Development Kit (SDK) contains conceptual overviews, programming tasks, samples, and references to guide you in developing solutions based on SharePoint products and technologies.
This program demonstrates some function approximation capabilities of a Radial Basis Function Network.
The user supplies a set of training points which represent some "sample" points for some arbitrary curve. Next, the user specifies the number of equally spaced gaussian centers and the variance for the network. Using the training samples, the weights multiplying each of the gaussian basis functions arecalculated using the pseudo-inverse (yielding the minimum least-squares solution). The resulting network is then used to approximate the function between the given "sample" points.
Address book helps you look up your addresses from the system tray.
It is quite useful in that way 慶ause it stays out of the way and is
easily accessible when needed. Double clicking on any URL will start
the default web browser and take you to that URL. Double clicking on
the phone number will dial that number. Every column supports
sorting and can be customized to your needs. Preview will display
the notes associated with each record.
This program can also import Comma Separated Values (*csv) text files
of Outlook Express.
function y_cum = cum2x (x,y, maxlag, nsamp, overlap, flag)
％CUM2X Cross-covariance
％ y_cum = cum2x (x,y,maxlag, samp_seg, overlap, flag)
％ x,y - data vectors/matrices with identical dimensions
％ if x,y are matrices, rather than vectors, columns are
％ assumed to correspond to independent realizations,
％ overlap is set to 0, and samp_seg to the row dimension.
％ maxlag - maximum lag to be computed [default = 0]
％ samp_seg - samples per segment [default = data_length]
％ overlap - percentage overlap of segments [default = 0]
％ overlap is clipped to the allowed range of [0,99].
In this edition, the majority of the book is dedicated to covering the Winsock API. Chapter 1 starts with an introduction to Winsock and is specifically geared for the beginning Winsock programmer. This chapter covers all the basics and introduces Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) through simple samples, as well as providing a roadmap to advanced Winsock topics covered in other chapters. For the sake of simplicity, Chapter 1 covers the IPv4 protocol.
This thorough, hands-on reference for database developers and administrators delivers expert guidance on sophisticated uses of Transact-SQL (T-SQL)¡ ª one of the most familiar and powerful programming languages for SQL Server. Written by a T-SQL guru, this guide focuses on language features and how they are interpreted and processed by the SQL Server execution engine. You¡ ¯ ll get in-depth coverage of the sophisticated uses of T-SQL, including triggers, user-defined functions, exception handling, and more. The book explains and compares solutions to database-development problems in both SQL Server 2000 and SQL Server 2005, discussing the new T-SQL programming features added to SQL Server 2005 in detail. Includes extensive code samples, table examples, and logic puzzles to help database developers and administrators understand the intricacies and help promote mastery of T-SQL.

The initial planning and thinking about this book began during a discussion of SQL Server futures in
July 2001. The discussion was with Rob Howard during a trip to Microsoft to discuss the first book I was
working on at that time. After that, I stayed involved in what was happening in ADO.NET by going to
the SQL Server Yukon Technical Preview in Bellevue, Washington, in February 2002 and by working
with the ASP.NET and SQL Server teams at Microsoft since July 2003.
