closed circuit

• Ein System, bei dem das Ausgangssignal auf den Eingang zurückgeführt wird und so einen geschlossenen Kreislauf bildet; häufig in der Elektrotechnik, bei Fernsehsystemen oder Überwachungskameras verwendet, bei denen das Signal nur an bestimmte Empfänger übertragen wird.

A system where the output is fed back into the input, creating a loop; commonly used in electrical engineering, television systems, or security cameras where the signal is transmitted only to specific receivers.
