TY - JOUR AU - Bartkevicius, S. PY - 1999/10/29 Y2 - 2024/03/29 TI - Periodic time-domain analysis based on approximation by splines and harmonic balance JF - Elektronika ir Elektrotechnika JA - ELEKTRON ELEKTROTECH VL - 23 IS - 5 SE - DO - UR - https://eejournal.ktu.lt/index.php/elt/article/view/16726 SP - AB - <span>A periodic solution of non-linear system represented by cubic spline may be expressed by a finite harmonic row exactly representing nodes of the spline. The differentiation operation on this row is replaced by multiplication by special matrix. New representation of a periodic solution allowing direct differentiation is proposed.</span> ER -
