Great video,thank you ~ ~ It is BP filter! And from Bode plot we can see fL = 3.18 hz and its stand for Low frequency can pass but High f wll be cut off. 🤔
@Electrical Engineering Topics I lost track of the part explaining frequency response derived from the transfer function. Could you explain more about it? I know s = sigma+jw but not sure how to get there from this definition.
Can you answer me this question: why does the load resistance have no effect on the transfer function whatsoever? Can I put any load resistance I want and it won't affect transfer function at all?
As long as the load resistor is large enough so that the maximum output current is not exceeded. Practical op-amps have limitations such as slew rate, input offset voltage, offset input current, maximum output current, ...
finally an engineer that doesn't write sloppy when students are trying to learn! Huge thanks!!!

You did a very good job of explaining a complex issue. Thumbs up. Keep em' coming. Thanks

Wow, Maybe I don't understand radical, but I will apply...... Thank you
Arab teachers are the best, thank you Professor ! (from Algeria)
Please someone tell me what 's' is ?
So what was the op-amp you chose ?
Great video! Thank you!
Everything makes sense except why we are using H(s)=-Z2/Z1? Is this a known formula or did we derive this from the circuit? Thanks!
If we look closely, the configuration is exactly that of an inverting amplifier, where Z2 is the feedback and Z1 is the input impedance.

What wiil change in the case if is a non-inverting band pass op-amp?
Hello,
The load resistance does not have any effect in your calculations?
Very grateful for this lesson thank you
Very good!
very good, but where are the gain ?
please explain why load resistor is used in band pass filter
Subscribed. Thank you.
Hi!
What is the 'S' ?
s is the one involved with laplace
S represent j*w
