Bad Fast Fourier Transfer (FFT) data captures can cause you to misunderstand the true performance of your analog-to-digital converter (ADC). Some engineers like to coherently sample and capture data ...

Among the most important questions radio managers and engineers soon may face is how to implement IBOC DAB technology. Radio World has asked Ibiquity Digital Radio to answer common IBOC questions in ...

Growing demands in wideband radio and wireless communication deployments are imposing the necessity of a proper radio architecture capable of providing solid performance, more flexibility, in addition ...

Coherent interleaved sampling is a new technique that can acquire data faster with more data points than sequential sampling. Engineers who need to characterize semiconductor devices, high-speed ...

Suppose you take a few measurements of a time-varying signal. Let’s say for concreteness that you have a microcontroller that reads some voltage 100 times per second. Collecting a bunch of data points ...

DSOs (digital oscilloscopes) offer a great many advantages over their analog equivalents but as they say, “There’s no such thing as a free lunch.” Digital scopes sample, digitize, and store waveforms ...

Sampling a signal causes the original signal spectrum (blue) to create sum (purple) and difference (red) frequencies around the sampling frequency, fS. When the difference signals fall into the ...
