数学与信息科学学院，C语言学习——高级进阶C语言学习高级教程(School of Mathematics and Information Science, C language learning- Senior Advanced C language learning advanced tutorials)

本书是由c语言的设计者brian w. kernighan和dennis m. ritchie编写的一部介绍标准c语言及其程序设计方法的权威性经典著作。全面、系统地讲述了c语言的各个特性及程序设计的基本方法，包括基本概念、类型和表达式、控制流、函数与程序结构、指针与数组、结构、输入与输出、unix系统接口、标准库等内容。 　　本书的讲述深入浅出，配合典型例证，通俗易懂，实用性强，适合作为大专院校计算机专业或非计算机专业的c语言教材，也可以作为从事计算机相关软硬件开发的技术人员的参考书。 在计算机发展的历史上，没有哪一种程序设计语言像c语言这样应用如此广泛(C language book is written by the designers of brian w. kernighan and dennis m. ritchie write a description of the standard c language and the authority of the program design classic. Comprehensive and systematic about the c language of all the basic features and programming methods, including basic concepts, types and expressions, control flow, function and program structure, pointers and arrays, structures, input and output, unix system interface, the standard library and so on. Book about simple terms, with a typical example, user-friendly, practical, suitable as a computer professional or computer professional colleges of the c language materials can also be as engaged in computer-related hardware and software technology developed by staff reference. In the history of computer development, no programming language such as c language so widely used)

本文通过对男性和女性声音的语音特征的研究，发现男女声的基音频率存在较大的差异，并设计了基于基音频率分析的男女声识别系统。男女声识别系统由以下三个模块电路构成：话筒放大器，低通滤波器，半波整流电路，单片机测量控制模块。话筒放大器采用NE5532P音前置芯片，对语音信号进行放大；八阶低通滤波器MAX293完成基音信号的提取；单片机STC12C5410AD实现频率测量和控制输出功能。经仿真与电路实测，男女声的识别效果良好。(In this paper, the voices of male and female voice characteristics of the findings of a study of the fundamental frequency of the sound of men and women there is a big difference, and the design of frequency analysis based on the pitch of the voice recognition system for men and women. Voice Recognition System for men and women from the circuit the following three modules: the microphone amplifier, low-pass filter, half-wave rectifier circuit, single-chip measurement control module. NE5532P sound using the microphone pre-amplifier chip amplification of voice signals eight MAX293-order low-pass filter to complete the extraction of pitch signal STC12C5410AD single-chip realization of the frequency of measurement and control output. By circuit simulation and measurement, the identification of male and female voices well.)
