Controls, Filters, Bandpass, Gain

Click For Summary
Unity gain at the center of the pass band in a closed-loop system can lead to stability issues, particularly if the open-loop gain is not properly managed. This situation is generally undesirable as it may result in oscillations or reduced performance. To improve this, one could adjust the feedback network or incorporate additional filtering to stabilize the system. However, these modifications may introduce phase shifts or affect the bandwidth, leading to potential trade-offs in performance. Overall, careful consideration of the system's design is crucial to maintain desired operational characteristics.

What is effect on closed loop when one has unity gain at the center of the pass band for an open loop ? Is this desirable? If not how could situation be improved? Are there any consequences for the suggested improvement?
