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

A variant of the sigma-delta ADC architecture, called the continuous-time sigma delta, has found homes in embedded applications such as mobile handsets for some time. Here's what you need to know to ...

Time crystals can be classified as either discrete or continuous. An external periodic force drives discrete time crystals, while continuous time crystals emerge from the collective and self-sustained ...

We develop an optimal quantization approach for numerically solving nonlinear filtering problems associated with discrete-time or continuous-time state processes and discrete-time observations. Two ...

Florian Bourgey and Julien Guyon introduce a novel discrete-time-continuous-time exact calibration method. They build an S&P 500/VIX jointly calibrated discrete-time model, which they later extend to ...

Most physicists honor Einstein’s insight, and so most approaches to quantum gravity take space and time to either both be continuous or both be discrete.
