In part 1 of this pair of articles, we ran SPICE noise simulations on a simple second order lowpass filter. We saw that there is something fundamental about the ‘hold’ that the filter’s capacitor ...

In the wonderful world of integrated circuits, filters play a key role in many important functions within a system design. There are many types of filter architectures from which to choose, but one of ...

Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...

In part one of a two part series, we unpack why digital equalizers and filters sound characteristically harsh. By Christian Luther. Digital filters (for instance, in equalizer plugins) traditionally ...
