Brilliantly explained the negative feedback concept with the awesome example of cruise control.. So novel and intuitive teaching.. Great Admiration for you Prof. Razavi Sir☺🥰
01:25 - Intro and Feedback Examples 08:55 - "Without feedback we have untamed and poorly-controlled circuits and systems" 18:30 - General Negative-Feedback System 18:55 - Four Components of a Negative-Feedback System 26:25 - Notes 34:00 - Transfer Function of a Closed-Loop System 41:00 - Quiz: Determen zhe Error Signal in Terms of X 44:20 - "If the error is minimized X and U are very close"
In the notes @27:00, shouldn't we require k > 0 - otherwise we can add X and U but still get the same result with k = - 1 ? EDIT: ah, you point that out at @38:00 :)
You are right. If "x" is excatly equal to "u", there is no output. But as it is said in the lecture, the feedback signal is a good copy of the input signal which means it is approximately equal. A1 is quite large, therefore there is a signal in the output which can be calculated as it is said.

Thank you sir! Your teaching is so much better then at Lunds Faculty of Engineering
Excellent..........feeling lucky... Thank You Sir...from India.
Sheer genius
so touching for an excellent video
Who really tried touching the fingers? 2.36
Thank you sir
Character In the video It's great, I like it a lot $$
1 hour later and I'm still trying to make my fingertips touch with my eyes closed.
😆
Thank you

The example with the speedometer will be much more clear, if the speed will be 88mph.
We don't want to see any more serious shit.
Because we are already watching it!!

when x=u, error =0. That means input to A1 is zero. then there should not be any output.
Thats only when you dont have any feedforawrd system A1. In such a case its meaningless.
You are right. If "x" is excatly equal to "u", there is no output. But as it is said in the lecture, the feedback signal is a good copy of the input signal which means it is approximately equal. A1 is quite large, therefore there is a signal in the output which can be calculated as it is said.
If there is no output, u is zero too. That means x and u cannot be equal.
2:42 I CAN ACTUALLY
That’s great. Add it to your resumé
This is groundbreaking. It changes everything. Its implications are far reaching.
