It is proved in this paper that this equivalentnoise model is neither equivalent to the original one nor measurable.
本文证明，这既不是相当于原来也没有可衡量的等效噪声模型。

The performance of a digital receiver will be changed significantly when the equivalentnoise temperature of the A/D module rises to hundred thousands degrees.
等效噪声温度高达数十万度的A/D模块，引起了数字接收机性能的深刻变化。
