Function Generator is a multi-wave signal source.
It can produce sine, square, triangle wave, or even arbitrary waveform.
It has a wide frequency range, the use of a wide range, is an indispensable source of GM.
It can be used for production testing, maintenance and laboratory equipment, but also widely used in other fields of science and technology, such as medicine, education, chemistry, communications, geophysics, industrial control, such as military and aerospace.
In this issue I function signal generator of the principle of learning, the design posed by the integrated operational amplifier circuit of the function waveform. I passed on the circuit analysis, parameter identification, select one of the most suitable for the subject program. In achieving the requirements under the premise of the subject to ensure the most economical, most convenient, the most optimized design strategy. Options in accordance with the design of the original concrete, welding specific physical map, and in the laboratory, weld a good kind of debugging plans to observe the effect and performance issues required for comparison. Finally, the analysis of the causes of error factor. This design as the core device chip 741 to produce a function signal generator, the lower the production costs. Suitable for measuring student learning using electronic technology.

The function generator is more than one kind of profile supply oscillator. It may have the sine wave, the square-wave, the triangular wave, even random profile. It has the very wide frequency range, the use scope is very broad, is one kind of essential general supply oscillator. May use in producing the test, the instrument service and the laboratory, but also widespread use in other tech area, like medicine, education, chemistry, communication, geophysics, industrial control, military and astronavigation and so on. in this topic I through to the function signal generating device's principle's study, designs transports by the integration puts the constitution the function profile to have the electric circuit. I through to electric circuit's analysis, the parameter determination, choose one kind most to suit this topic the plan. In meets the topic requirements under the premise to guarantee that is most economical, is most convenient, the optimized design strategy. According to the design plan choice concrete original part, welds the specific chart in kind, and carries on the debugging in the laboratory butt weld good chart in kind, the observation effect and makes the contrast with the topic request performance index. The ultimate analysis presents error's reason as well as the influencing factor. This design take 741 integrated blocks as the core component, manufactures one kind of function signal generating device, the manufacture cost is low. Suits the student to study the electronic technology survey use.

The function generator is one kind of much wave form signal source. It can produce sine wave , Fang Bo , triangle wave, even arbitrarily wave form. That it has very broad frequency range , uses range to expand very much, is the signal source being applied or used universally be not allowed to be short of one kind. Can be used to produce the testing, instrument being maintained preparing a laboratory , be put into use fairly broadly in other science and technology field, if medical education, chemistry , communication , geophysics , industrial control , military affairs and astronavigation etc.I pass the study about to function generator principle in the problem , design that circuit happened in the function wave form putting in formation from integrated luck out. I pass to circuital analysis , parametric ascertaining that, scheme choosing one kind of be suitable for most this problem's out. Design tactics ensuring that most, economy, is the most convenient , optimize most on the premise of call for in 函数发生器是一种多波形的信号源。它可以产生正弦波、方波、三角波，甚至任意波形。它具有很宽的频率范围，使用范围很广，是一种不可缺少的通用信号源。可以用于生产测试、仪器维修和实验室，还广泛使用在其它科技领域，如医学、教育、化学、通讯、地球物理学、工业控制、军事和宇航等。
在本课题中我通过对函数信号发生器的原理的学习，设计出由集成运放构成的函数波形发生电路。我通过对电路的分析、参数的确定，选择出一种最适合本课题的方案。在达到课题要求的前提下保证最经济、最方便、最优化的设计策略。按照设计的方案选择具体的原件，焊接出具体的实物图，并在实验室对焊接好的实物图进行调试，观察效果并与课题要求的性能指标作对比。最后分析出现误差的原因以及影响因素。本设计以741集成块为核心器件，制作一种函数信号发生器，制作成本较低。适合学生学习电子技术测量使用。

reaching a problem. According to that the scheme designing that chooses concrete original copy, solder out concrete material object picture, in and the laboratory carries out a debugging on to soldering good material object picture, observe effect and do contrast with the function index that the problem demands. The at last error cause and influencing factor appears on analysis. Design the component centering on 741 integrated pieces originally , make one kind of function generator , make cost comparatively low. The electron technology the student suitable is learned from measures usage.
