Negative feedback is a universal control mechanism that lets a system's output throttle its input. If an engine revs up, negative feedback tapers its power source. But if the engine slows down, it ...
Engineers use feedback loops — typically negative feedback is more useful, but positive feedback is needed for oscillators.
Among all power factor correction (PFC) topologies, totem-pole bridgeless PFC provides the best efficiency; therefore, it is widely used in servers and data centers. However, closing the current ...
A recent Ahead of the Tape column concerned how a "negative feedback loop" describes what it means when things keep going from bad to worse. But in response to the column, several readers argued that ...
Many physiological behaviours of cells are repeated periodically in time, such as hormone secretion, second messenger signalling, cell-division cycles and circadian rhythms. Oscillatory behaviour is a ...
