Hittade en liten föklaring på elektrisk rundgång: "In electronics, feedback is defined as the process of returning part of the signal output from a circuit or device back to the input of that circuit or device. ... In positive feedback control systems, the positive feedback is in phase with the input, which makes the output larger, i.e., results in system gain."
Så electronic feedback heter det på engelska tydligen. Simple as that.
