GND (ground)

Guest pawl21

Sunt foarte incepator in acest subiect si as vrea sa va intreb unde si cum sa leg GND-ul intr-un circuit ?

Despre ce circuit este vorba? De obicei spunem "masa" ( gnd ), la potentialul la care se raporteaza fiecare punct din circuit, de exemplu, alimentare simetrica +/-20V, spunem ca avem o tensiune pozitiva de 20v si alta negativa de 20v, ambele raportate la un potential comun numit masa ( gnd ). Un alt exemplu, un amplificator comandat cu un semnal de intrare de 0,5vrms, adica pe intrarea amplificatorului se introduce un semnal de 0,5vRMS raportat tot la masa... si exemplele pot continua.
