There are many different (and often confusing) terms associated with clock-based devices. This application note attempts to clarify these terms, and hence serves as a comprehensive reference on clock terminology. This application note can be divided into two sections. The first section describes and distinguishes between various clock sources available today. The second section defines and distinguishes between various parameters used to describe clocks. This section also provides methods of measuring some of these parameters.

51单片机C语言的编程技巧 在进行单片机应用系统设计时．汇编语言是一种常用的软件工具。它能直接操作硬件．指令的执行速度快。但其指令繁育统的固有格式受硬件结构的限制很大．且难于编写与调试．同时其可移植性也较差。随着单片机硬件性能的提高．其工作速度越来越快．因此在编写单片机应用系统程序时．更着重于程序本身的编写效率。本文介招的C51交叉编译器就是解决连一问题的利器-51 microcontroller C programming language skills during SCM application system design. Assembly Language is a common software tools. It can directly operate the hardware. Order Execution speed. But their breeding EC Directive format by the inherent structural limitations of hardware great. It is not easy to prepare and debugging. While its portability also poor. With SCM performance of hardware. Their work ever faster. Therefore, in preparing microcontroller applications procedures. More focused on the preparation process itself efficiency. This paper introduces the C51 cross compiler is not even solve the problem of a sharp object

这篇实验报告是关于单片机多路数据采集的，本实验由2大部分组成：1、为用EPOROM构成的心电信号发生器；2、为多路信号的微机采集与显示；第一部分实验主要研究可编程序存储器EPROM的非计算机应用。把存储在EPROM中的数字心电信号读出并通过D/A转换为模拟信号显示在示波器屏幕上。 第二部分实验的目的是研究一个数据采集系统，该系统利用ECD-51型单片机为中心，由D/A芯片等将各种低频信号以及由EPROM产生的模拟人体心电信号变换成离散的数字信号存入微机内存，以待进行数据处理和分析，然后再通过D/A转换将其还原成模拟信号显示在示波器的屏幕上。 -This experimental report on the multi-SCM data acquisition, the experiment by the two major components : 1. EPOROM pose for the use of the ECG signal generator; 2, multi-path signals in the computer acquisition and display; the first major study of experimental programmable EPROM memory in non-computer applications. Stored in the EPROM of ECG read out by D/A conversion of analog signals displayed on the oscilloscope screen on. Part II The purpose of this experiment is to study a data acquisition system, which uses ECD-51 microprocessor as the center, from the D/A chips, and other various low-frequency signal from EPROM and the simulation of human ECG transform into several discrete signal words into computer mem
