    @ibrahimabdi299 ปีที่แล้ว

    I watched this TH-cam video about phase margin and gain margin, but I must admit that I was a bit confused and couldn't fully understand the concepts being discussed. It's possible that the video was intended for a more advanced audience, or the presenter didn't explain the ideas in a way that's accessible to beginners like me.
    I also noticed that some people in the comments were applauding the presenter's explanation, which made me wonder if I'm missing something. However, I understand that everyone has different levels of understanding and familiarity with the topic, so it's possible that they had a better grasp of the concepts.
    If anyone has any resources or recommendations for learning about phase margin and gain margin, I would greatly appreciate it! I'm eager to learn and understand these concepts better.

    • @kwgm8578
      @kwgm8578 ปีที่แล้ว

      @ibrahimabdi -- this is 8 year old video, not likely to get an answer from the TA who has no doubt, found a paying job! These are concepts from a Control Theory class, (call it CT), which Electrical Engineering students must study as a junior or senior in their undergraduate training.
      The idea of CT is to move a complex system described by differential equations, out of the time domain, into an imaginary domain -- the frequency domain -- via a Laplace Transform. Or, if you wish to work with a discrete domain, the Z Transform.
      My point in supplying these details is to demonstrate that it requires advanced math training to get the big picture of CT.
      I wish you the best of luck with your education.

  • @lolPirate

    For separating the real and imaginary part, don't we have to rationalize the fraction?

    • @Jnglfvr
      @Jnglfvr 3 ปีที่แล้ว +1

      Yes but the result is the same. Multiply both numerator and denominator by the complex conjugate of the denominator and then setting the imaginary part of the resultant numerator to zero you get the same formula.

  • @sanhitaguin9683
    @sanhitaguin9683 9 ปีที่แล้ว +22

    shouldn't the imaginary part be obtained by multiplying the denominator and numerator by the conjugate of the denominator? because we can't separate fraction in two fractions, one the imaginary and the other the real part, till the denominator isn't expressed in factorised form and the numerator is an algebraic sum of real and imaginary part

    Just one query: For Phase crossover frequency, you said to equate the Im[G(jw)]=0. But actually you equated the imaginary part of the denominator of G(jw) to 0, i.e, without rationalizing G(jw). So, please clarify you mean to equate the denominator only or the whole rationalized transfer function.
