摘要
测井技术的发展把载波数据传输系统引入到测井仪器中。本文在简单对比了调幅、调频和调相方法之后,较详细地介绍了用于测井的相移键控系统。
The development of well logging technology leads to the installation of carrier data transmission system in logging apparatus. After a brief comparison of AM (Amplitude Mod-ulation), FM (Frequency Modulation) and PM (Phase Modulation), this paper gives a de-tailed analysis of PSK (Phase Shift Keying).
