Continuous Feedback a. Consider a variation on the above intermittent feedback device. Place tub TA on a device that continuously m0onitors the weight of the water in the tub and, thereby indirectly, the amount or level of water in the tub. In this example, flow rates will not remain fixed, nor will a faucet either is completely open or closed. The flow rates can vary continuously in response to the level of the water in the tub.
Feedback is now continuous.
The way in which the level affects the rate of flow into or out of the tub determines whether the feedback is viewed as positive or negative. A System Operating With Continuous Positive Feedback a. Definition - Positive feedback is feedback, which tends to amplify the process, which gave rise to it. The water level will continue to rise and it will do so at an increasing rate because the faucet is continuously being opened more and more. Figure H below shows the graphic portrayal of this situation.
