Getting around that issue used to require a splitter and second mixer just for recording.
游览用来记录所需要的只是一个和第二混频器，分配器问题。
Second , the noise of double balanced mixer was analyzed, which involved analysis of low frequency flicker noise and high frequency thermal noise.
接着对双平衡混频器的噪声进行理论分析，包括低频闪烁噪声和高频热噪声。
We computed the input impedance of mixer with the first method, and we also discussed the effect of the convergent parameter on improving the convergence with the second method.
用第一种方法求出了混频器的输入阻抗，用第二种方法讨论了收敛参量对改进收敛性的影响。
