摘要
本文叙述一种新颖的多功能智能杂音仪,它除具有杂音仪的功能外,还可测量载波系统的失真度。本文简单介绍了该仪器的测量原理,阐述了所用的主要技术:有源滤波器设计,模拟测量电路,8031单片机软硬件系统,自检自校过程,抗干扰设计等等。
A new multifunctional Intelligent Psophometer is described. The psophometer is used also to measure distortion of carrier communication system. The measurement principles of this psophometer is introduced simply. Main techniques used by the meter are shown, for example, design of active filters, analogue measuring circuit, software and hardware system of single chip microcomputer 8031, process of autocorrection and automatic self-test, design of anti-interference and etc.
