The wavelet coefficients in high frequency sub band distribute near the zero values symmetrically; 高频段小波系数都对称分布在零值附近;
The amplitude of negative frequency components of multiple analytical band pass filter is zero, which can greatly reduce the demand for character of digital filter, increase the maximum multiple of Zoom analysis and improve the accuracy of Zoom spectrum analysis. 复解析滤波器的负频率部分幅值为零,能够大大降低对数字滤波器特性的要求,提高细化分析的最大倍数和细化谱分析的精度。
Most optical oscillator strengths for the transitions between valence band and conduction band are nearly equal to zero. 价带顶和导带底附近的带间跃迁振子强度大部分都近乎为零;
As long as the reject band is not equal to zero in transmitting or receiving terminals, signals will produce adjacent frequency leakage. 在通信发射和接收端的滤波器阻带因子非零的情形下,信号会产生邻频泄漏。
Theoretical calculation was performed and it is found that the stress of TiO2 / SiO2 narrow band interference filters may be zero. 同时还分析了TiO2/SiO2滤光片的应力特性,发现该滤光片存在零应力的可能。
