Thus the electrode has only an indirect influence on the feedback circuit.

This, in turn, would increase the cirrus cloud cover, effectively creating a positive feedback circuit.

It also hurt like hell, and he had to turn down the feedback circuit until the arm felt nearly dead.

As the earth moves, the electronics attempt to hold the mass steady through a feedback circuit.

Many common designs simply use an incandescent lamp or a thermistor in the feedback circuit.

This type of feedback circuit evolved into what is now known as a phase-locked loop.

"You said there was a feedback circuit that let this shuttle fly?"

The feedback circuit passes current into the cell to reduce the error signal to zero.

The feedback circuit controls the electromagnet to try and keep the suspended object at the correct position.

One of the feedback circuits seems to drop control data.
