Se poate folosi un sumator cu operational.Dar in orice caz nu merge cu alimentare la 5V. Gandestete ca la semnalul tau vrei sa aduni 5V,asta inseamna semnal de iesire peste 5V ceea ce nu poti sa scoti din alimentare la 5V,decat cu ceva in comutatie care sa-ti ridice tensiunea si nu cred ca se justifica complicatia.Mai bine zi cat e impedanta de iesire a sursei tale de semnal si am sa postez apoi o schema sa discutam la obiect.PS: Daca semnalul are numai componenta alternativa se poate face si pasiv;da mai multe detalii despre ce vrei sa faci!
