This is pretty much why electricity only flows in closed loop circuits.
Closed loop circuits ensure that the desired position is precisely reached.
The term loop disconnect dialing arises from its nature of interrupting the local loop circuit.
Current loop circuits are one possible way used to control radio base stations at distant sites.
The office would have a remote control unit that would operate the taxi company base station over a current loop circuit.
This changes the total inductance of the loop circuit.
This ability to "lock on" in the presence of noise is central to the utility of the phase-locked loop electronic circuit.
Since there is no feedback from the output to either input, this is an open loop circuit acting as a comparator.
The autocross event involves an open loop circuit designed with chicanes, speed traps and slaloms.
Phase detectors for phase-locked loop circuits may be classified in two types.
