摘要

摘要:本文介绍了一种数字域微分器的设计及其低噪声实现。利用粒子群算法和模拟退火算法的混合优化技术，实现了L1误差目标函数的最小化。与现有设计相比，获得的幅度响应提供了理想微分器的值得注意的近似，具有最小的幅度误差。本文还对各实现结构的噪声增益特性进行了研究和比较。

Optimal design and low noise realization of digital differentiator

Abstract This manuscript presents a design of a differentiator in the digital domain with its low noise realization. It manifests the minimization of the L1 -error objective function by using a hybrid optimization technique consisting of the particle swarm and simulated annealing optimization algorithm. The obtained magnitude response provides a noteworthy approximation of the ideal differentiator with a minimal magnitude inaccuracy when compared with the existing designs. The realization structures are also investigated and compared in terms of the noise gain behavior.
