This lecture is an introduction to frequency response methods, and in particular describes the Bode plot. I go through how it is generated and why we use it to visualize the frequency response of a system across the entire frequency spectrum.

Errata:
8:31 - I should not have combined both time domain and s-domain in a single equation.
9:31 - it should be 2 - j*1/omega, I correct it at 9:55 but don't let it confuse you!

I will be loading a new video each week and welcome suggestions for new topics. Please leave a comment or question below and I will do my best to address it. Thanks for watching!

Which is the software you use for whiteboard? I want to see whether a a better software will make my drawing skill better. ha ha..

Hi Brian, fantastic lecture and really appreciate your time taken to explain the origins of decibels as well. Quick question, at 1000 in the video, how comes the imaginary component is 2 when your expression is 2 - (1/omega)i ?

I replayed the section explaining the history of decibel unit many times because I was easily distracted by your skilled drawings haha. Thank you for creating clear and fun educational videos!

Love your videos, they are always super insightful!
One remark though: When expanding the a sinx +b cosx identity, isn't the phase shift ρ supposed to be atan(a/b)?

After a 9 years I feel dumb I became a frontend engineer :'( my uni was just too predatory for students to flourish. Your teachings were the best though :) Always thought me to like linear systems theory. :) sad that very few company seeking control engineers here in Czechia. 😢

In the LTI video, you explained homogeneity, superposition and time invariance. However, I do not see how these properties imply property 3 (integrable) and 2 (differentiable). Could you elaborate on that? Great video! :)

xD
hate the way you say Laplace :v
i know it's a picky thing but you say it "lapLACE" and it sounds weird to me xd
i say it "LAPlace" and to me it sounds a lot cooler that i even use it a lot in games :y
