What is the range of the system stability chart?

The range of the system stability chart typically refers to the spectrum of frequencies over which a system's stability can be analyzed. This chart often depicts stability margins, such as gain and phase margins, across different frequencies. In control theory, the range is crucial for understanding how the system responds to various inputs and disturbances, identifying stable and unstable regions of operation. It's important to note that the specific range can vary depending on the system being analyzed and the parameters used in the chart.
