- I'm confused about the differences between H(ω) and H(s). The textbook defines both as transfer functions though the transfer function is mostly reserved for H(s).

Hi,

I'm confused between H(ω) and H(s) as transfer functions. The textbook defines both as transfer functions though the term transfer function is mostly reserved for H(s) as far as I can tell. I have read that poles and zeroes of H(s) are helpful in determining the stability. Are poles and zeros of H(ω) also related to stability? Can it be said that H(s) determines the stability during transient state and H(ω) during steady state?

Could you please give it a look and comment on it?

Thank you!
