Filter Basics: Anti-Aliasing - AN928
In a sampled data system, frequency components greater than half the sampling rate "alias" (shift) into the frequency band of interest. Most of the time, aliasing in an undesirable side effect, so the "undersampled" higher frequencies are simply filtered out before the A/D stage. But sometimes, the undersampling is deliberate and the aliasing causes the A/D system to function as a mixer. This a...
متن کاملMulti Criteria Sampled-data H∞ Control Applied to the Choice of Sampling Rate and Anti-alias Filter
A systematic evaluation procedure for the choice of sampling rate and anti-alias filter in sampled-data control is presented. It is based on a multi criteria H∞ optimization procedure, where sampled-data measures are introduced to capture the intersample behavior. The optimization scheme is based on linear matrix inequalities (LMIs) formulated in the delta operator, and the result is a low orde...
متن کاملThe basics of anti-aliasing: using switched-capacitor filters - AN3494
Aliasing due to unwanted, spurious out-of-band signals is a problem in many applications that use A/D converters. These signals, if not filtered properly, can seriously impact the performance of a data-conversion system. This application note discusses the principles of anti-aliasing and its effect on system performance. It also offers advice, via an elegant and cost-effective, completesystem e...

متن کاملA Framework for Generalized Sampled-data Control Systems and Its Application to Convergence Analysis a Framework for Generalized Sampled-data Control Systems and Its Application to Convergence Analysis
This paper presents a framework for sampled-data control systems with generalized samplers and holds. This framework is advantageous in the point that it covers a large class of generalized samplers and holds and also in the point that it treats samplers and holds in a symmetrical manner. Using this framework, converging and non-converging properties of sampled-data control are investigated. Th...
