In this video, we demonstrate a handy trick to determine gain and phase margin using a scientific calculator without the need to plot a Bode plot. Gain and phase margins are crucial parameters in control systems design, indicating stability and performance. By following our step-by-step guide, you'll learn how to input transfer function coefficients into your scientific calculator and use its functions to directly calculate gain and phase margins. This time-saving method provides a practical alternative for engineers and students who need quick stability analysis without graphical plotting.
