Final answer:
In a feedback system with measurement noise, the system provides feedback based on measurements with added noise. Measurement noise can introduce random errors or uncertainty into the measurement process, affecting the accuracy of the feedback. Accounting for measurement noise is important to ensure accurate and reliable operation.
Step-by-step explanation:
In a feedback system with measurement noise, the system provides feedback based on measurements with added noise. This means that when the system takes measurements, there is some random error or noise introduced into the measurement process, which can affect the accuracy of the feedback.
For example, let's say you have a temperature control system that measures the temperature in a room and adjusts the heating or cooling accordingly. In a feedback system with measurement noise, there may be some error or uncertainty in the temperature measurement, which can affect the accuracy of the system's response.
It's important to account for measurement noise in feedback systems to ensure accurate and reliable operation.
