| Abstract: | Periodic oscillation is established in nonlinear networks N. Its sufficient and necessary conditions are to possess an equivalent model, which satisfies power balance conditions P=0, Q=0. The model is result from superposition of infinite linear microcoonstitaents N{jk}. Therefore at least there is an infinitesimal component N{jk} to satisfy P{jk}≤0 and Q{jk}≤0. If each and every infinitesimal component is P{jk}>0 or Q{jk}>0, the result from superposition in sure P>0 or Q>0. Then the networks, which comprise nonlinear amplifers, can not produce any periodic oscillations of whatever waveforms. |
