提出了一种设计具有各种类型约束的线性和任意相位有限脉冲响应（FIR）滤波器的新技术，该方法基于向量空间投影方法。我们描述约束集及其关联的投影，以捕获所需滤波器的属性。在滤波器设计中，与许多其他工程问题一样，人们主要感兴趣的是满足设计约束，即找到一种可行的解决方案，不一定是最佳解决方案。向量空间投影方法非常适合此目的。我提供了许多通过向量空间投影进行 E-IR 滤波器设计的示例，包括重要且困难的任意相位/幅度问题。提供了证明该方法相对于其他已知方法的优点和灵活性的示例。
A new technique for designing linear and arbitrary-phase finite-impulse response (FIR) filters with various types of constraints is proposed, The approach is based on the method of vector space projections. We describe the constraint sets and their associated projections that capture the properties of the desired filters. In filter design, as in many other engineering problems, one is primarily interested in meeting design constraints, i.e., finding a feasible solution, not necessarily an optimum one. Vector space projection methods are well-suited for this purpose. me furnish numerous examples of E-IR filter design by vector space projections, including the important and difficult arbitrary phase/magnitude problem. Examples that demonstrate the advantages and flexibility of this method over other known methods are furnished.
