Practical use of the method of finding forced periodic modes, described in the previous chapter, has two difficulties. First, for a pulse modulation of the second kind, the solvability of the equations of periods is insufficient for the existence of a periodic mode. Some additional research is required. Secondly, if a period of an external action S2 is N times greater than the sampling period T, then, instead of one equation of periods, we obtain a system of N transcendental equations, whose solution becomes substantially more complicated with the increase of N.
