A Bode plot shows how a system responds across frequencies: magnitude in decibels above, phase below. The gain and phase margins — how far the curves sit from instability at the crossover — predict whether closing the loop stays stable. Educational tool.

Governing equation

H (j ω) = \frac{1}{( 1 + j \frac{ω}{1} ) ( 1 + j \frac{ω}{10} )} \Rightarrow ∣ H ∣ = - 0.0 dB, ∠ H = - 1^{\circ}

Reading this result: A healthy 179° phase margin means the loop closes with plenty of stability and little overshoot.
