frequency window function的意思|示意

In any event, the measured frequency response function will be affected by the window and leakage that does result.

无论如何，测得的频响函数必将受到窗函数和泄漏的影响。

The residual side-lobes of the frequency response can be effectively suppressed by employing the window function technique, using Hannin.

采用窗函数技术可以有效地抑制具有坡度的同轴布喇格结构的频率响应曲线的残余旁瓣。

In fact, the FFT spectrum is the convolution between read time series and window function in domain of frequency, the dominant frequency position influence on leakage should not be ignored.

由于实际信号和窗函数在频域为卷积关系，所以应该考虑实际频率在FFT谱上所处的位置。

Compared with the amplitude-frequency characteristic of the window functions often used at present, its property has an advantage over the rising-cosine function improved.

与目前常用的几种窗函数的频率特性相比较，其性能优于改进的升余弦窗函数。

A window function which has a flat top in frequency domain is designed to correct the amplitude error caused by Picket_Fence effect.

并从减小栅栏效应带来的幅值估计误差的角度，设计了一个具有平顶窗谱的窗函数，分析对比了它和矩形窗函数的性能差异。
