摘要
ＺＩＣ型智能音频综合测试仪是供广播电台使用的音频系统测试仪器。它采用微型计算机进行数据处理、逻辑控制，用快速付立叶变换产生正弦波音频信号。本仪器可测量音频系统的失真、频率响应、噪声、抖晃率等。本文叙述了该仪器的工作原理。
The intelligent audio measuring set Type ZIC is designed for broadcasting station use to measure the distortion,frcquency response,noise,wow and flutter etc. of an audio system.The data processing,logic control,the FFT analysis of sine wave audio signal are all controlled by micro computer. This paper deals with the operational principles of this measuring set.
