Hello Nigel,I am planning to imlpement a Biquad IIR filter on an FPGA platform. Right now, I’m searching for a simple yet useful Audio Application for the biquad filter. I would like to ask for your suggestions.Thanks,Marika
As for applications, I suggest that searching the internet will give a better answer than I can in short space. However, I do suggest that you pay close attention to your math precision—the standard biquads can be very sensitive to coefficient rounding and math precision, especially when set to lower frequencies.
This blog has been so helpful, I will be patiently awaiting your next post!
Thanks, son.
Here here, I second that. It would also be great to read some articles related to amp simulation, your area of specialty!
Thanks for stopping by, Dallas—I’ll put your request on my to-do list

Great blog! Thanks!
Ear Level Engineering rocks! It’s the best link between the maths of DSP and implementable DSP algorithms/concepts I’ve ever found!
PS After all those great articles on dithering and resampling, can you do a post on bandlimited oscillators?
