本文主要对无理函数的阻抗函数(或导纳函数)综合为无源网络的问题进行了系统的理论分析和推导,并从以下三个方面进行论述:综合方法、正确性以及在载波通信中的具体应用。如用无源网络实现的阻抗函数是一无理函数,则由于工程上物理可实现条件的限制,无理函数的阻抗函数不能采用有理函数的阻抗函数所采用的综合方法。此时,可以采用一种近似方法,此近似方法能以要求的精确度用有理函数的综合方法来实现。文中以综合法设计自动电平调节系统中的调节网络为例,说明了该方法在载波通信中的应用,简要地推导和论述了综合法设计变阻型第Ⅱ类可变幅度均衡器的设计原理和设计方法,并给出了设计实例。
In this dissertation, the impedance functions (or admittance functions) of irrational functions are synthetically analyzed and deduced systematically for the problem of passive networks. The following three aspects are discussed: synthesis method, correctness, application. If the impedance function implemented by passive network is an irrational function, the impedance function of irrational function can not adopt the comprehensive method adopted by the impedance function of rational function due to the limitation of physically achievable conditions in engineering. In this case, an approximation method can be used which can be realized by an integrated method of rational functions with the required accuracy. In this paper, an example is given to design a regulation network in the automatic level control system by the integrated method. The application of the method in carrier communication is illustrated. The design of the variable-resistance type Ⅱ variable amplitude equalizer Principle and design method, and gives the design examples.
