Digital filter can be divided into analoguefilter with two digital filter.
数字滤波器可分为模拟滤波器与数字滤波器两种。
2
The analoguefilter is configured to cancel the predistortion of the feedback signal.
模 拟滤波器被配置成消除反馈信号的预失真。
3
The variable impedance scaling method for design of SCN has been improved in the Paper, the resulting is that the analoguefilter can be realized by Passive SCN.
