muuntolaite
A muuntolaite, meaning "converter device" in Finnish, is a general term for an electronic device that changes an electrical signal from one form to another. This transformation can involve various aspects of the electrical signal, such as voltage, current, frequency, or signal type (e.g., analog to digital). The specific function of a muuntolaite depends entirely on its intended application.
Common examples of muuntolaite include power adapters that convert household alternating current (AC) to direct current
