Closed
loop checking is perform before cable termination..the difference between a close loop and open loop is,tha close loop has a feedback while the open loop has not.
no.
no difference that's the difference
Distortion is estimated as closed loop gain divided by open loop gain. If the open loop gain approaches infinity, distortion approaches zero.
A practical opamp is designed to approach the characteristics of the ideal opamp as closely as possible. The open loop voltage gain of an ideal opamp is infinite, so while this is actually impossible to achieve practical opamps are built with as high an open loop voltage gain as possible.
One can close an open circuit by adding a complete loop of wire. This will allow the electricity to flow through the circuit, while electricity will not flow in an open circuit.
An open loop transfer function is the transfer function of a system without incorporating the feedback component. For example, where the closed loop transfer function with unity feedback H(s) = G(s)/(1+G(s)) it can be deduced that the open loop transfer function is Y(s)/U(s) = G(s).
it is when a control loop is open and processing
The sensitivity of an open loop control system is always 1, it is due to no feedback involved in open loop.
an open circuit.
The system without feedback is known as open loop system. The examples of the open loop system are bread toaster, oven ,washing machine. The open loop systems are inaccurate & less complex.
if we set timimg for cooking rice then it is open loopbut thermostat in electric cooker can not give more temmp, than 100deg. so some microprocessor is controlling here .thus in this case it will act as closed loop system.
