Why use FIR filters, anyway? With the availability of easy-to-use IIR filters in Cypress Semiconductor’s PSoC Creator’s Filter tool, I’ve spent a lot of time over the years telling people the ways in ...

This application note presents the MLX90614 on-chip digital signal filters focusing on the on-chip signal-filtering feature part of the integrated circuit. It also describes the filter configuration ...

Previous columns have described how analog and switched-capacitors filters work and provided a real example of each. Now on to digital filters that process discrete-time digital values, rather than ...

The first part of this series described how data flows through processing steps that create a moving average of stock prices over 65 days. Finite-impulse-response (FIR) filters use the same data-flow ...

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 ...

Let’s say you chose a particular microcontroller for its 12-bit analog-to-digital converter (ADC). You built up your system, and although the ADC gives you 12 bits of resolution, the lower couple of ...
