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 ...

Easy adaptation to several mobile communications standards is a design goal for wireless communications transceivers, where end users require low cost, low power, and small device size. We can achieve ...

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 ...

Digital upconverters (DUCs) and digital downconverters (DDCs) are important components of every modern wireless base station design. While many DUC and DDC designs are available, there is a clear call ...

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 ...

The Zoom FFT is interesting because it blends complex down conversion, lowpass filtering, and sample rate change through decimation in a spectrum analysis application. The Zoom FFT method of spectrum ...
