N\u00ebse ndryshoni gjendjen e hyrjes s\u00eb linj\u00ebs s\u00eb vones\u00ebs nga 0 n\u00eb 1, at\u00ebher\u00eb 1 n\u00eb dalje do t\u00eb shfaqet jo menj\u00ebher\u00eb, por vet\u00ebm pas nj\u00eb kohe t\u00eb caktuar. N\u00eb rastin ton\u00eb, kjo \u00ebsht\u00eb 3 sekonda. Po ashtu, n\u00ebse ndryshoni gjendjen e hyrjes s\u00eb linj\u00ebs s\u00eb vones\u00ebs nga 1 n\u00eb 0, at\u00ebher\u00eb 0 n\u00eb dalje do t\u00eb shfaqet pas po atyre 3 sekondave.

Le t\u00eb supozojm\u00eb se fillimisht n\u00eb daljen e linj\u00ebs s\u00eb vones\u00ebs ishte 0. Pas kalimit n\u00eb nyj\u00ebn B \u2014 invertori \u2014 kjo 0 shnd\u00ebrrohet n\u00eb 1 dhe hyn n\u00eb linj\u00ebn e vones\u00ebs. Fillimisht, nuk ndodh asgj\u00eb. N\u00eb daljen e linj\u00ebs s\u00eb vones\u00ebs si\u00e7 ishte 0 ashtu mbetet, por fillon gjithashtu num\u00ebrimi i koh\u00ebs s\u00eb vones\u00ebs. Kalojn\u00eb 3 sekonda. Dhe menj\u00ebher\u00eb linja e vones\u00ebs gjeneron nj\u00eb ngjarje. N\u00eb daljen e saj shfaqet 1. Ky nj\u00ebri, pas kalimit n\u00eb nyj\u00ebn B \u2014 invertori \u2014 shnd\u00ebrrohet n\u00eb 0 dhe hyn n\u00eb linj\u00ebn e vones\u00ebs. Kalojn\u00eb edhe 3 sekonda\u2026 dhe procesi p\u00ebrs\u00ebritet. Pra, \u00e7do 3 sekonda, gjendja e daljes s\u00eb linj\u00ebs s\u00eb vones\u00ebs ndryshon nga 0 n\u00eb 1 dhe m\u00eb pas nga 1 n\u00eb 0. Rele vjen n\u00eb jet\u00eb. Generatori punon. Periudha e impulsve \u00ebsht\u00eb 6 sekonda (3 sekonda p\u00ebr daljen zero dhe 3 sekonda \u2014 nj\u00ebsi).<\/p>\n

Por, n\u00eb skemat reale, zakonisht nuk \u00ebsht\u00eb e nevojshme t\u00eb p\u00ebrdoret edhe ky shembull.
