Multi-rate processing and sample rate conversion, or interpolation and decimation as they re known, are a clever digital signal processing (DSP) techniques that broadband and wireless design engineers ...

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 ...

The critical component in all digital communications receivers is the analog-to-digital converter (ADC). The ADC sampling rate, bandwidth, and noise tolerance establishes the specifications and ...

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 ...

Scattering-type scanning near-field optical microscopy (s-SNOM) allows spectroscopic imaging with spatial resolution below the diffraction limit. With suitable light sources, s-SNOM is instrumental in ...

Forbes contributors publish independent expert analyses and insights. I write about the broad intersection of data and society. Deep learning has become the dominate lens through which machines ...
