摘要: 提出了一种实现宽带信号实时采样的技术原理和应用设计方法;论述了混合滤波器组技术对传统并行交替采样结构进行非均匀采样的校准处理,多通道采样的时钟与触发同步机制,以及分相存储实现大容量采样数据存储等研究内容;给出了系统的可行性设计。Abstract: This paper presents a design method for Wide-Band Signal Sampling (WBSS). Hybrid filter banks, unique clock distribution and multi phase storage are discussed for considering high precision, synchronized sampling and mass samples storage. Consequently, a design of WBSS based on above techniques is presented and its hardware prototype is realized with a 12 bit, 200 Msa/s for applications of WBSS.
