An errata for the stability condition for the second order all pass section with transfer function H(z)=(c2+c1*z^-1+z^-2)/(1+c1*z^-1+c2*z^-2), the two conditions are abs(c2)<1 and abs(c1)<1+c2, not abs(c1)<1 as stated in the post.

There is no short cut to understanding how to properly implement filters with FPGA technology.

Of course, all AI engines rely on hardware to drive their incompetence [emoticon:44a8a53ad3364ea78a16c5a3229f75bb].

I came across a video the other day which discussed the use of FPGA design for handling neural networks (needed for AI). I've been dying to know, just how practical a solution is this considering the complexity of simple FPGA design (well to me anyway).

Useful info - thanks.

I found a nice paper for C coders:
