Electrical Engineering: Ch 15: Frequency Response (2 of 56) What is a Transfer Function? 2 of 3

In this video I will explain what is a transfer function using simple circuits and how it is associated with the transfer function which is frequency dependent.

Next video in this series can be seen at:

SIR - U R THE BEST ON EVERY TOPIC - U R THE BEST ON THIS TOPIC -THANK U FOR EXCELLENT LECTURES

I would prefer this video to have subtitles so I and people that are hard of hearing can follow the FR lecture.

At 3:09 you say " as frequency goes to infinity, the Capacitor acts as an "Open Circuit". Shouldn't this be a "Short Circuit"

Hello Michael, please consider making video on processing of earthquake time-history signals, finding the fourier transforms/power density functions, making artificial earthquake time histories that also match design response spectrum specify by code (International building code, the IBC, ASCE7-16, etc, Thank you.

Omega=R/L meanes Inductors are like short curcuits at low frequencies and impedance increases with frequency, because Inductors oppose changes in current.. X=2pi•Hz•L
Omega=1/RC means Capacitors are like open circuits at high frequncies and impedance decreases as frenquency increases, because it doesnt have time to charge all the way. X=1/(2pi•Hz•C)
Incase you didnt get that the first time, I didnt

3:10 Not like an open circuit, but like a short circuit. I guess, he misspoke.

I think this is good material, but covered way too fast. I may try some different sources and then come back watch it again to see if it makes sense.

Sir, why is a Transfer function =0.707 at omega-naught of special significance? I'm having a hard time finding the answer to this. Thanks.

I think in your definition on the board you spelled Transfer wrong.
