摘　　要：根据广播电台和录音棚的相位检测需求,利用模拟乘法器的鉴相功能,设计出一种专业音频立体声相位测量仪,有效避免了音频节目生产过程中的反相问题。To fulfill the practical demand of correlation detect from broadcasting station and record workroom, a professional audio correlation detector is designed, based on the phase demodulation function of analog multiplier. This detector can efficiently resolve the problem of anti-phase happened in the stereo audio program manufacturing process.

关 键 词：立体声相位测量 反相 模拟乘法器 三角鉴相
