表面波抽头延迟线是一种信号处理器件。它可作为相位编码友形发生器和匹配滤波器用于扩频技术中的扩频调制和解调。本文介绍表面波抽头延迟线在扩频通信中的应用以及使用表面皮抽头延迟线进行的话音信号扩频传输实验。
Surface wave tap delay line is a signal processing device. It can be used as a phase-coded friendly generator and a matched filter for spread spectrum modulation and demodulation in spread spectrum techniques. This article describes the application of surface-wave tapped delay lines in spread-spectrum communication and the spread-spectrum transmission of voice signals using surface-tapped delay lines.
