Digital instruments sample analog waveforms and operate on the samples with the assurance that the data can be restored to continuous analog form. The sampling theorem states that a signal digitized ...

Design linear discrete-time systems and filters and analyze their behavior. Represent continuous-time signals and linear systems in discrete time, so that such signals can be recovered in continuous ...

Comprehensive introduction to analysis of continuous and discrete-time signals and systems. Linear time-invariant systems, convolution; Fourier series representations of periodic signals; Continuous ...

High-frequency financial data are not only discretely sampled in time but the time separating successive observations is often random. We analyze the consequences of this dual feature of the data when ...

Observing non-repetitive and statistically rare signals that occur on short timescales requires fast real-time measurements that exceed the speed, precision and record length of conventional ...

Sigma-delta converters are widely used today in applications demanding high precision and accuracy. A variant of the sigma-delta architecture, called the continuous-time sigma delta (CT-S?), has long ...
