single frequency noise meaning in English
单频噪声
Examples
- The experiment results show that the single frequency noise can be reduced 7db ( a ) , and the broad - band random noise can be reduced effectively in assigned frequency band
实验对单频噪声取得了7db ( a )的降噪效果,对宽频噪声则能在指定频带上取得较好的降噪效果。 - Secondly , ground on the duct noise control , the delayed - lms algorithm , which is actulized easily , is brought forward , then the simulation on pc is achieved . it is shown from the computer simulation that for the single frequency noise , there will be a good effect when choosing the suitable parameters ; but for the narrowband noise , the effect will become worse with increasement of the bandwidth . this result is helpful to analyze the parameters influencing anc
结果表明： ( 1 )随着滤波器长度的增大，系统收敛速度变快； ( 2 )随着值的增大，系统的收敛速度增大，但是当值超过某一范围时会引起系统的发散； ( 3 )次级通路的延迟数与初级噪声频率有关； ( 4 )对于窄带信号， dlms算法可以取得一定的降噪量，但是随着窄带信号带宽的增大，降噪效果明显变差。
