ADC Digital Downconverter: Decimation Filters and ADC Aliasing, Part 2

In part one of this blog series, ADC Digital Downconverter: Decimation Filters and ADC Aliasing, Part 1 we began looking at the decimation filtering in the DDC when the complex to real conversion is ...

Use Software Filters To Reduce ADC Noise

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 ...

Build SincK Decimators

The data is accumulated and a new output (Result) is available for every 16 inputs. In this case, the data throughput has been decimated by a factor of “16.” Although the data rate has also been ...

ADC Digital Downconverter: Decimation Filters and ADC Aliasing, Part 1

Over the last few blogs we’ve been looking at DDCs and how frequencies are shifted and folded in the output spectrum. In the last blog, ADC Digital Downconverter: A Complex Decimation Example we ...
