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 ...

Clear filters are a valuable tool for photographers working in harsh environments and are a wise addition to any photographer's kit. Positioned in front of the lens, they provide an extra layer of ...

Most embedded engineers writing firmware have used some sort of digital filters to clean up data coming from various inputs such as ADCs, sensors with digital outputs, other processors, etc. Many ...

State-space digital filters constitute a versatile class of algorithms used to process signals by modelling dynamic systems through state variables. Their representation encompasses both the system’s ...

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 ...
