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.
然后为其设计了信号放大、滤波和调零电路；
Secondly, a current for it is developed, which consists of a bridge zero modulation current, signal amplifier and analog filter.
这种器件最有效地使用于调零和光束置中应用，目标通过保持平衡或调零信号来维护或监测光学器件的对准。
These devices are most effectively used in nulling and beam centering applications where the goal is to maintain or monitor optical alignment by keeping a balanced or null signal.
