- Feedback systems are designed to reduce noise and nonlinear distortion by utilizing techniques to sample the output, compare it to the input, and then adjust the output accordingly.
- The goal is to ensure that the introduced noise is as low as possible compared to the amount reduced by the feedback amplifier. This helps in maintaining a high signal-to-noise ratio and minimizes the impact of noise on the overall system performance.
Here, option 2 is correct.
