与原有的LUM滤波器相比,它能缩短程序运行的时间,较好地降噪,保护图像的有用信息,更好地增强图像的边缘。
Comparing with original LUM filter, it can shorten the running time of the program, reduce the noise, keep the useful information and enhance the edge of the image.
同时,计算机仿真说明,只要参考输入中信号分量较少,自噪声有源抵消器仍然可以达到较好的降噪效果。
Computer simulations also validate that the good attenuation effect can be obtained in the active self noise canceler if the signal component in the reference input is small.
实验结果表明,该装置回收排气余热量大,和原消声器相比,排气阻力较小,降噪效果明显。
The test results show that it can recover much more exhaust heat, and less exhaust resistance and lower noise than the original one.
