如果不进行“调零”修正,所产生的偏置量就会叠加到输入信号上产生误差。
Unless it's corrected by "zeroing," the resulting offset produces an error by adding to the input signal.
在目前这个设计中,阶跃输入信号限制在零点几毫伏以下。
In the present design, step inputs are restricted to a few tenths of millivolt.
该滤波器通过处理输入离散采样信号获得连续信号并抑制谐波噪声,改进了过零测频方法。
The filter processes input discrete sampling signal to recover continuous signal and suppress harmonic noise, and the zero-crossing frequency measuring method is improved.
