一、直接序列PSK声表面编码器和译码器声表面波器件近年来已为大家所熟悉,它可以制作成滤波器、延迟线、抽头延迟线、卷积器、声电卷积器、弹性卷积器等等。它的发展对扩频技术产生深远的影响,本文将着重介绍声表面波抽头延迟线在扩频技术中的 First, direct sequence PSK surface acoustic wave encoders and decoders SAW devices have become familiar to everyone in recent years, it can be made into filters, delay lines, tapped delay lines, convolvers, acoustic convolvers, flexible Convolver and more. Its development has a profound impact on the spread spectrum technology, this article will focus on the SAW tapped delay line in the spread spectrum technology
