The Analysis of Linear Periodically-Time-Variable Circuits by the Frequency Symbolic Method with Application the D-Trees Method

In this paper we analyze the application of the matrix equation of L. A. Zadeh to symbolic analysis of the LPTV circuits in the frequency domain. The symbolic solution of the linear algebraic equations is proposed to be performed by the socalled the d-trees method. The main provisions of the d-trees method are analyzed. The examples that convince the high efficiency of the method of d-trees are given. The results are used in the design of amplifiers of special purpose.
