The paper presents the procedures of tolerance analysis and optimization of linear periodically time-variable circuits, based on the frequency symbolic method and realized by the system of functions MAOPCs in an environment MATLAB. The peculiarity of tolerance analysis and circuit optimization consists in the fact that previously the assessment of asymptotic stability of the investigated linear periodically time-variable circuit within the given limits of changes of circuit parameters is carried out and the permissible areas of their change in which the circuit is stable are determined. Exclusively in these areas tolerance analysis and optimization is realized.
