FAQ

What should I read from a Bode plot?
Look at gain margin, phase margin, crossover frequency, and resonance peaks. They indicate speed, stability margin, and noise amplification risk.
How do root locus and Bode plots differ?
Root locus shows pole movement as gain changes. Bode plots show gain and phase versus frequency. They give different design viewpoints.
Why group control and filter tools here?
Both use frequency response to reason about amplitude, phase, stability, and bandwidth, so cross-links are useful.
