    Can IIR FIlters Be Fully Pipelined? We have reached the final post in this series on LWDF IIR filters. I hope that I was able to convince you that many, if not all, of the perceived disadvantages of IIR filters can be addressed while maintaining thei...

    Look Ma, no multipliers! The last LWDF IIR filter example I gave was unusual in the sense that it was multiplierless, all the coefficients were powers of two, which in FPGA hardware cost absolutely nothing. Of course, this restricts considerably the ...

    Linear Phase IIR Filters? Part 3 Finally, the third and probably most efficient, but also least known and used way to achieve near linear phase IIR filters is the object of this post.  Absolute linear phase, or equivalently constant group delay,...

    Linear Phase IIR Filters? Part 1 I hope everybody can agree by now that IIR filters, especially in their LWDF form, are at least interesting and worth a look. I mean, an order of magnitude on average less resources compared with an equivalent FIR has...

    LWDF IIRs I am finally ready now to discuss the LWDF IIR filter architecture.  In a few words, such a filter consists of two parallel all pass sections, which differ in order by 1, which means that one path is of odd order while the other one is...

    Why IIR Filters? Now I am going to switch gears from FIRs to their poorer and much less famous cousins, IIR filters. Recursive or Infinite Impulse Response filters tend to have a very bad reputation and are rarely used compared with Non-Recursive, Fi...
