The flow graph at 0:22 on the numerator side doesn’t make sense. The direction of the delay is correct, but it’s on the wrong side + fix direction of the right node where w[n] converges and moves towards the y[n] node.
I know this is 2 years old, but I think he means to change the definition of a1. like if it is 5, change it to -5. `float a = 5; a = -a;` if this were programming. If you are being a mathematical purist just find another variable like a0

Shouldn't there be a negative sign in front of the summation for the aks summation @4:21?
What do you mean by "redefine a coefficients?" How is that legal?

@@markpoe2846 "mathematical purist", I like that, thanks for add this to my vocabulary, I'll be using it a lot.
how did you factorized the denominator
Great tutorial, keep up the good work!
Do you have any videos on Parallel and Cascade Form Flow Graphs? Thank you.
Jack Zhang
Thank you very much!, but I havea question, what is the name of the software you use for making these videos?
beautiful explanation
Thank you! Helped a lot!
Oh and lovely video too!
Good job
this is direct form for IIR filter
I think there is an error the first time you drew the graph. The zero block arrows weren't all in the right direction.
