A variety of ultrawideband system designs — from carrierless, impulse UWB (I-UWB) to multicarrier (MC) UWB — have been pursued recently. I-UWB has several advantages, including simple RF circuitry, ...

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 ...

The launch of new products and options during June has boosted engineers’ choices for both time- and frequency-domain analyses. In the latter category, Anritsu added differential noise-figure ...

When evaluating the dynamic performance of precision analog-to-digital converters (ADCs) using fast Fourier transform (FFT) analysis, coherent sampling typically is used to accurately measure the ...
