Anti-aliasing may refer to any of a number of techniques to combat the problems of aliasing in a sampled signal such as a digital image or digital audio recording. Specific topics in anti-aliasing include: • Anti-aliasing filter, a filter used before a signal sampler, to restrict the bandwidth of a signal such as in audio applications

Diagnostic systems typically work from data sampled at a lower rate than that used for process control. As a result, aliasing is a concern. This is especially an issue in monitoring systems for the process industries, because of the prevalence of control loops that cause cycling. broadbeach sports and spinal
