基于数/模转换器的信号发生器原理与设计

Principle and design of signal generator based on digital-analog converter.

信号源是科研人员常用的设备之一。特别是地震勘探仪器的使用和维修常常要用到不同精度的信号源。本文从信号发生器的原理出发,阐述了一种新型高精度信号源的原理和制作方法,对从事物探仪器的技术人员进行仪器的检测和维修、信号源的制作有很好的借鉴作用。

The signal generator is one of common-used instrument for scientific research personnel. Especially, the signal generators in different precision are often used for use and maintenance of seismic apparatus. Starting from the principle of signal generator, the paper illustrated the principle and manufactured method for a new type of high-precision signal generator, which give a good reference to technicians of geophysical apparatus that engaged in test and maintenance of apparatus and manufacture of signal generator.
