噪声系数通常用于衡量一个电路和或者系统内部噪声大小，它通常用于比较不同电路或者系统噪声性能的好坏。噪声系数的定义如下： An amplifier is usually picked exactly where its sound contribution is negligible when compared with the resource resistance by using a figure of benefit, RS, OP, of the op amp. It may be calculated through the use of an amplifier’s sound specification. The relationsh... https://ramseye455gzu9.like-blogs.com/profile
