【Abstract】 A quanitative discussion on the relation between the optimum source resistance of noise and the maximum power transmission of transistor amplifier at the low and middle frequency is given in the paper.An approach of realizing simultaneously the optimum noise ratio and the matched resistance is presented, and the correlation coefficient between E_n and I_n of common. emitter amplifier is analysed.更多还原
