Filtering occurs frequently in the analog world. Unfortunately, in the digital world, engineers apply it mainly to the DSPs (digital-signal processors) and not to the small 8-bit microcontrollers that ...

This idea details a design method for making anti-aliasing prefilter parameter tradeoffs between several factors. These factors include the filter pass-band magnitude accuracy, the filter order (the ...

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 ...

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 ...
