It is the same procedure, as explained starting at 6:45. Those imaginary roots outside the unit circle are reflected back inside the circle. Say they are at +- j1.1, then they get reflected to -+ j (1/1.1) in step 2 as poles in H_{ap}. Then they get added as zeros (at -+j(1/1.1) ) to H_{min}
I did the last example with you, and I don't understand how you managed to get -0.81 in the Hmin section. If you take out the "beta" from the zeros in Hap you get 1/0.9, not 0.9. So shouldn't Hmin be -1/0.81 ??
Is it true that single zero and pole are not mirror image, but the pair of zeros and poles are mirror image. It is because pole=r*e^(jw) and zero=1/r*e^(-jw). The angle of zero and pole are actually conjugate.
You are correct. Thanks for being so careful and letting me know about the error. I've annotated the video to reflect the correction.

Namaste from India🙏🙏
thnks fr this lecture, its awesme nd easy to understand the concepts of all pass nd min phase system..
Thanks Barry for the reply, you made me less worried for my exam haha.

The corrected link seems to be broken, the annotation leads nowhere.

Great , thanks
what type of controller can be used for non minimum phase s/m?
Good question. I'm not a control theory experts, so I don't have the answer for you at this point in time. Someone else out there might know though.
