摘要
各种电器设备要正常工作，常常需要各种波形信号的支持。电器设备中常用
的信号有正弦波、矩形波、三角波等。在电器设备中，这些信号是由波形产生和
变换电路来提供的。这种能够产生多种波形，如三角波、矩形波（含方波）、正
弦波的电路被称为函数信号发生器。函数信号发生器产生的各种波形能满足现代
测量、通信、自动控制和热加工、音视频设备及数字系统等对各种信号源的需求。
例如设计和测试、汽车制造、生物医药、传感器仿真、制造模型等。在生产实践
和科 技领域中有着广泛的应用。

Abstract
A variety of electrical equipment to work properly, which often need the support
from a variety of wave form signals. Electrical equipment commonly used in signal
sine wave, square wave, triangle wave. In electrical equipment, these signals are
generated by the waveform and the conversion circuit to provide. This can produce a
variety of waveforms such as triangular wave, rectangular wave (including square),
the sine wave signal generator circuit is called a function. Function generator for a
variety of waveforms to meet the modern measurement, communications, automatic
control and thermal processing, audio and video equipment and digital systems, the
demand for a variety of sources, such as design and testing, automotive, biomedical,
sensor simulation, manufacturing model. Production practices and technology in the
field has a wide range of applications.
Key words: Sine wave, Square wave, Triangle wave, The function signal generator.
