基于单片机C8051F060的电成像系统激励信号源的设计

DESIGN OF THE GENERATOR OF THE ELECTRONIC IMAGING SYSTEM CONTROLLED BY C8051F060 CHIP-MICROCOMPUTER

设计了一种基于单片机C8051F060的井下仪器发射激励信号源，利用单片机内部功能模块——-DAC模块，产生PWM脉冲序列，再经过功率放大器放大，然后将滤波解调出的标准正弦波作为电成像成像测井系统极板的发射激励信号源。基于单片机的集成化模块为测井仪器中信号源的研制提供了新的方法。

Design a downhole tools generator controlled by A C8051F060 chip microcomputer,which uses it's internal timer. Generating a PWM signal,and though amplifing by Power Amplifiers and filtering,producing standard sine wave.The attempt offers a new method of downhole tools generator.
