In many applications, you need to apply a post-processing digital filter on your data. A common example is the filtering of data from an ADC. This application note shows an IIR filter that can be ...

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 ...

In “Why DAC and ADC responses droop,” we looked at the two common places where the sinc() function crops up in a data acquisition system. A DAC with zero-order hold has a frequency response that ...
