各位达人, 求翻译成英文~
与模拟滤波相比,数字滤波具有很多突出的优点,如:它可以满足滤波器对幅度和相位特性的严格要求,可以避免模拟滤波无法克服的电压漂移、温度漂移和噪声等问题.其中 FIR滤波器具有以下优点: ①具有严格的线性相位 ,同时又具有任意的幅度特性; ②单位样值响应是有限长的 ,因而系统一定是稳定的; ③可以用快速傅里叶变换 ( FFT)算法来实现 FIR滤波,从而可大大提高运算效率.

A lot of advantages of digital filtration rather than analog filtration such as it can strictly meet requirement from filter to extent and phase as well as evitable the problems like drift voltage,temperature and noise which are impossible over come by analog filtration.Among of them,the filter FIR has the following advantages
[1]Both have strictly linear phase system and have random amplitude transmission characteristic
[2]Must be stabilized system as limited unit sample response
[3] Thus it would be made computational efficiency much better.as can be used FFT algorithm to contribute FIR filter.
因为很多专业术语有固定译法,本人不属于专业人士,只是意译.希望能对你有所帮助.
