Phase retrieval in holographic data storage by expanded spectrum combined with dynamic sampling method is proposed, which serves to both reduce media consumption and to shorten the iterative number of ...

Sigma-delta converters are in wide use among applications that demand high precision and accuracy. A variant of the sigma-delta architecture, called the continuous-time sigma delta (CT-S?), has found ...

Nyquist pulse generation underpins modern high-speed optical communications by producing sinc-shaped waveforms that occupy the minimum spectral bandwidth for a given data rate. These pulses, ...
