问 Slew rate defines an amplifier’s maximum rate of output
excursion. This specification sets limits on undistorted
bandwidth, an important capability in A/D driver applications.
Slew rate also influences achievable performance in
D/A output stages, filters, video amplification and data
acquisition. Because of its importance, amplifier slew rate
must be verified by measurement. Deriving a measurement
approach requires understanding slew rate’s relationship
to amplifier dynamics.


帮偶看看这段话大概讲什么，谢谢，谢谢，谢谢。 答 1: 试试：Slew rate defines an amplifier’s maximum rate of output

摆率（有些也叫做转换速度、回转速度等）说明了一个放大器输出端的最大变化速率。
它限制了在AD驱动器应用中的一个重要性能——不失真带宽。
在DA输出级、滤波器、视频放大及数据采集中，摆率同样也影响着性能的可实现性。
因为它的重要性，放大器的摆率必须要用仪表来校验。
测量方法的获得，需要理解放大器动态特性与摆率之间的关系。
答 2: 比较难一点的是excursion一词Slew rate defines an amplifier's maximum rate of output excursion.

压摆率，最好叫电压转换速率，字面意义直观，到位。 答 3: re压摆率决定了放大器输出的最大摆动速率. 这个指标限制了在AD驱动器应用中非常重要的非失真带宽性能. 压摆率还会影响A/D输出级、滤波器、视频放大及数据采集等应用所能达到的性能. 鉴于它的重要性, 放大器的压摆率必须进行测量检验, 所用测量方法应以对放大器动态性能与压摆率的关系的理解为基础.
