本文叙述了几种可供选择的利用集成电荷耦合程控横向滤波器实现的自适应滤波器的设计与结构。特别强调既要从理论观点又要从实验观点来分析系统结构的误差。其主要目的是为了证明:有高性能规范的自适应滤波器尽管其组成元件的误差界限很大,但利用电荷耦合器件(CCD)可以非常简便地实现。为此,对滤波器的性能进行了把主要误差原因考虑在内的全面的理论分析;文中还提供了实验结果,证明用原型系统实际上可取得高性能。对全模拟和模-数混合实现型式的优缺点作了鉴定,并对其具体的应用范围进行了讨论。
This article describes several alternative designs and structures of adaptive filters implemented using integrated charge-coupled programmable lateral filters. Special emphasis should be analyzed both from the theoretical point of view and from the experimental point of view of system structure error. Its main purpose is to demonstrate that adaptive filters with high performance specifications are very easy to implement with charge-coupled devices (CCDs), despite the large error margin of their components. To this end, the performance of the filter was taken into account the main reason for the error, including a comprehensive theoretical analysis; the paper also provides experimental results to prove that the prototype system can actually obtain high performance. The advantages and disadvantages of the full analog and analog-digital hybrid implementations were identified, and their specific applications were discussed.
