提出了设计用于对模拟系统（它们是模拟和数字混合音频信号处理的组成部分）的频域特性（如幅度和相位响应）进行均衡的数字滤波器。数值实例向人们展示了采用数字滤波器进行均衡带来的优越性。介绍了几种音频方面的应用（如反折叠滤波器、扬声器均衡和型数据变换器的均衡）。研究了一些密切相关的课题，如高效多速率滤波器构造、参数建模以及递归数字滤波器与非递归数字滤波器的比较。 A digital filter designed to equalize the frequency-domain characteristics (such as amplitude and phase response) of analog systems that are part of analog and digital mixed audio signal processing has been proposed. The numerical examples show people the advantages of using digital filters to balance. Several audio applications are introduced (eg, anti-aliasing filters, speaker equalization, and type data converter equalization). Some closely related topics are studied, such as efficient multi-rate filter construction, parametric modeling, and comparison of recursive and non-recursive digital filters.
