Been going to a chief engineer's filter design class for about 4 weeks now. Watched Active Filters #1-3 so far, I am planning on going in and teaching my chief Engineer's class myself. Thank you for this amazing video series. SUBSCRIBED :)

Very Good explanation.. really learnt a lot

[@phillipneal8194]

Great presentation. But what op-amp should I use ?

You are a very good teacher. Thank you! Can you please tell me the textbook from where you got the K values for the Butterworth Designs.

According to your explanation. Sir I've made a second class sallen key low pass filter with unity gain using lm324 quad op amp on single supply, but when I adjust the gain to 1.5 by using feedback , I get no output or very less output signal .

Thank you!
A question, if I want to implement a chebyshev sallen key filter what are the coefficients?
