144N. Zero-value time and transfer constants (ZVT), b1 and a1 term calculation 

Best explanation ever exists for OCTC technique, you are perfect

Thank you so much Professor for the lectures. Hope you will visit Pakistan someday for guest lectures.

Could we say that time constants are decoupled from each other (and therefor can be factored) when they have no shared (or common) resistance in their individual time constants?

You have taken N th order system but the number of Poles you have taken N'(5:52).... So, is it true that order of the system = Number of Poles? Apart from that, you have taken Number of Time constant = Order of the system (19:03)... So, what is correct? Another doubt is: Who is greater? Number of Time constant or Number of Pole

At 31:40, I thought that C_u should be connected between the gate and the drain, not the drain to ground.

At 23:00, do we have two poles and and no zero here? But isn't it true that number of poles and number of zeros are always equal? Can we say we have two zeroes but they are at infinity here? Please correct me if I am wrong. Also, does "zero at infinity" tell anything more?
