Modern Digital Filter Design | Advice from an expert

Modern digital filter design is key to extracting the data we need from our noisy world. But where do we start? What must we take into account before beginning to design a digital filter? What tools are there out there to help us?

In this video, I am joined by Dr. Sanjeev Sarpal, an expert on digital filter design, the CEO of a company that specializes in AI and data analysis, and the inventor of the ASN Filter Designer. We discuss the challenges he faced in filter design, the tools he used along the way, how to choose the right filter for your design, and what led him to write his own digital filter designing tool.

The video includes a practical demonstration of how to design a digital filter to extract heart rate data from a PPG sensor.

As an audio engineer this is incredible I use filters every day and although I’ve done my research on such filters this gives a great fresh perspective.

your videos are one of the best I have ever seen on YouTube to understand math. Please, don't stop doing this !

Your videos are much more better, intuitive and easier to understand than the posts on Patreon. I wish every post would have a corresponding video, then i will return to patreon

Hi mark, i love your videos. I was wondering if it was possible to model the Earth using Fourier Series.
