The modern, advanced CMOS direct radio frequency (RF)-sampling data converter has been eagerly awaited by system design engineers for several major end-equipment manufacturers. This includes ...

Communications receiver architecture has evolved slowly over the years. The most common and successful configuration is the superheterodyne architecture, which translates the incoming signal to a ...

Many systems divide a crystal frequency by an integer number to generate clock signals. Unfortunately, the integer divisor limits the available set of output frequencies. Applications such as ...

Recently, I wrote automated test software for a multichannel data-acquisition system that I had designed, where sampled waveform accuracy and repeatability were very important. The input waveforms ...
