We're living the audiophile dream! Our phones can hold a year's worth of music and stream more songs than anyone could listen to in a lifetime. But none of that would be possible without the efforts ...

The concept behind digitizing sound. Working at Bell Labs, Harry Nyquist discovered that it was not necessary to capture the entire analog waveform, and samples of the wave could be taken at various ...

Primer on Nyquist and aliasing applied to the design of input filters for ADCs. Sampling a signal causes the original signal spectrum (blue) to create sum (purple) and difference (red) frequencies ...

Wideband signal processing and compressive sensing represent transformative approaches to the acquisition and reconstruction of signals across expansive frequency bands. Traditional methods that ...

Therefore, by bandlimiting the system with a band-pass filter, knowing the nyquist rate of the sampling system and the bandwidth of the signals of interest, one can reconstruct the input signal under ...
