A comparison of discrete-time (DT loop filter) versus continuous-time (CT loop filter) modulator systems. This second-order CT-S? ADC is shown with representative signal and noise transfer functions.

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

Represent continuous-time signals and linear systems in discrete time, so that such signals can be recovered in continuous time when necessary. Compute approximations to Fourier transforms of ...

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 ...

Did you know that you can use LTspice to do Digital Signal Processing (DSP)? Actually, I should say it is useful for validating the operation of a signal-processing algorithm under development. This ...
