场同步分离电路行脉冲抑制系数的拉氏分析

Laplace Analysis for Horizontal Sync Supression Coeficient in Vertical Sync Pulse Separation Circuit

应用拉氏变换方法分析和比较单节、二节、三节积分场同步分离电路的行脉冲抑制系数及其场同步输出，得出二节积分为最理想的场同步分离电路．

The horizontal sync supression coeficient and the vertical sync out in single stage,two stage and three stage vertical sync integrator circuits has analysed and compared with Laplace transform,therefore obstained result that two stage vertical sync integrator circuits is bast.
