linear system frequency response 线性系统频率响应
By which linear and nonlinear frequency response function was estimated, and nonlinear stiffness coefficient and damping coefficient of the model were optimized by least square method in this paper.
利用该方法对非线性频响函数进行估计，并利用了最小二乘法对模型的非线性刚度系数和非线性阻尼系数进行了优化。
Linear distortion - frequency response, polar response, resonance - affects primarily the timbre and clarity of a loudspeaker.
线性失真-频率响应，指向性响应，共振，主要影响音色和清晰度。
Advantage is relatively easy to produce, linear, and distortion of small, wide frequency response.
优点是制作相对容易，线性好、失真小、频响宽。
