摘要
本文主要分析了放大器的噪声对信号的影响及影响程度,介绍了衡量放大器的噪声对信号影响程度的参数,噪声系数,以及噪声系数的定义即而可计算出放大器的内部噪声．对放大器的噪声有进一步的了解,为分析或设计放大器提供了参考依据．
This article has mainly analyzed the amplifier noise to the influence of signal and the influence degree, Introduced weighs the amplifier the noise to the signal influence parameter -noise factor, As well as noise factor definition, computational method, Namely but may calculate lends out the great talent internal noiseHas the further understanding to the amplifier noise, In order to analyze or designs the amplifier to provide the reference .
