In feedback systems loop gain, open loop gain, and closed loop gain are all concepts that are important to understand. The transfer function for closed loop gain is: The quantity A is known as the ...

Researchers propose a novel closed-loop system merging brain-computer interfaces and peripheral nerve stimulation to enable ...

Neurofeedback is a type of biofeedback in which neural activity is measured and presented through one or more sensory channels to the participant in real time to facilitate self-regulation of the ...

Many neurological and psychiatric diseases are associated with clinically detectable, altered brain dynamics. The aberrant brain activity, in principle, can be restored through electrical stimulation.

Switching power supplies rely on feedback control loops to ensure that the required voltage and current are maintained under varying load conditions. Design of the feedback control loop influences ...
