Sir you have cleared lot of puzzles in my mind. You explained this topic in a very fine way. May ALLAH bless you 😊

hello brother, can you give me your email i want to ask you something

[@zinhaboussi]

very intuitive lecture thanks prof

[@saicharanmarrivada5077]

Finally ,I understood how to draw Bode plot.

[@phzhao5132]

I think the phase plot for the 1 zero and 2 pole example is wrong. The slope should be -90 between w=10 and w=100 due to the addition of the two poles phase.

[@MarkHuntingRats]

a little bit mistake at 58:15, the second segment of overall phase plot should be -90 degree,

👌👌

Hello sir, My instructor mentioned that at cut off frequency the point is a half power point. Can you describe why is that?

[@coolwinder]

So if we had only imaginary pole complex conjugate pair (pole on jw axis), we would have infinite Q, that is infinite peaking at that frequency and instant transition in phase of 90°? What does that mean (resonance)? If we had a double pole there peaking would take longer to stifle, and we would have 180° phase transition, what would that mean for resonance?

Thank you sir

I don't see how taking 1/10th of the bell to get the decibel equates to multiplying the bell by a factor of 10, would you not divide by 10 to get the dB relationship ? :)

[@AliHajimiriChannel]

If a piece of wood is 3 meters long, and if you wanted to state that length in cm, would you multiply by 100 or divide? Hope this helps.

[@rishabhchana5101]

sir, actually at a zero , the transfer function goes to zero, but that is not reflected in bode plot. Why ?
