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 ...
Basic review of how the different kinds of analog-to-ditital converters wor, with a sidebar relating them to appropriate applications. ADCs quantize time-varying analog voltages into a sequence of ...
A look at the Nyquist sampling theorem. How to deal with aliasing by attenuating signals using low-pass filters (i.e., an antialiasing filter, or AAF). AAF requirements for different ADCs. A deep dive ...
Power requirements for high-performance microprocessors have become increasingly demanding (see Figure 1). Prior to the Pentium class of processors, 5 Volts directly from the AC-DC silver box was used ...
ADI has introduced an alias-free ADC that aims to simplify front-end design and speed up time to market for precision DC-350kHz applications. Traditional precision data-acquisition signal chain design ...
Precision signal chain designers are challenged to meet noise performance demands in medium bandwidth applications and often end up making a trade-off between noise performance and accuracy. Achieving ...
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 ...
