现场总线是用于过程控制现场仪表与控制室之间的一个标准的、开放的、双向的多站数字通信系统。随着计算机技术、通讯技术、集成电路技术的发展，以全数字式现场总线（FIELDBUS）为代表的互联规范，正在迅猛发展和扩大。由于采用现场总线将使控制系统结构简单，系统安装费用减少并且易于维护；用户可以自由选择不同厂商、不同品牌的现场设备达到最佳的系统集成等一系列的优点，现场总线技术正越来越受到人们的重视。--Fieldbus is a standard, open, bi-directional multiple station digital communication system between field equipments and control room.

函数发生器是一种在科研和生产中经常用到的基本波形产生器，集成函数 波形发生器一般都采用ICL8038或5G8038，而它们只能产生300kHz以下的中低频正弦波、矩形波和三角波，且频率与占空比不能单独调节，从而给使用带来很大不便。本文介绍由LM324和稳压管组成的低频函数波形发生器，该电路能够产生正弦波、方波和三角波信号，频率能以10Hz的间隔在20Hz～20KHz范围内调整。-Function Generator is a scientific research and production often use the basic waveform generator, integrated function waveform generator usually used ICL8038 or 5G8038, and they only have a 300kHz following the low-frequency sine wave, square wave and triangular wave, and frequency and duty cycle alone is not regulated, so as to enable using bring a lot of inconvenience. This paper introduces the LM324 voltage regulator tubes, and the low-frequency waveform generator function, the circuit can produce sine, square and triangular wave signal frequencies of 10Hz to 20Hz at intervals within ~ 20KHz adjustment.

基于单片机处理的方式的数字示波器是以单片机为控制中心，通过对采样电路的控制进行波形实时采样、数据处理和存储显示-Microcontroller-based ways to handle the digital oscilloscope is a single-chip microcomputer control center, through the control of the sampling circuit waveforms real-time sampling, data processing and storage display
