Abstract：It was proved that the linear relationship between input and output entropy,and the entropy model of linear amplifier was given in the entropy domain.The noise entropy of sensor information could be elimina-ted by the process of the linear network to the greatest extent,so as to improve the resolution of the information source.The engineering example showed the contribution between the system noise coefficient and amount of information were different for all levels noise coefficient in low noise amplifier.The lower the equivalent noise coefficient,the greater the mutual information in the multi-stage amplification system.
