In signal processing systems, aliasing is normally treated as a disturbing signal. That motivates the need for effective analog, optical and digital anti-aliasing filters. However, aliasing also conveys valuable information on the signal above the Nyquist frequency. Hence, an effective processing of ...
In digital signal processing, spatial anti-aliasing is a system of practice for reducing the deformation work of art known as aliasing when representing a high-resolution image at a lower resolution. Anti-aliasing is used in digital photography, computer graphics, digital audio, and a lot of ...
Analog/Digital Conversions Howard Austerlitz, in Data Acquisition Techniques Using PCs (Second Edition), 2003 Aliasing When a signal is sampled too slowly (it contains frequency components above the Nyquist frequency), the digitized waveform is distorted. This distortion is called aliasing. It is the...

Firstly, we develop constraints on the aliasingfree sampling frequency via first-order sampling. Then, sufficient conditions are given to reconstruct a ... L Guo,CW Kok,HC So,... - 《Digital Signal Processing》 被引量: 0发表: 2022年 加载更多来源...
For example, in the realm of digital signal processing, it refers to an analog filter that only lets in a certain sample of the desired frequency range. The term is also used in photography. But in this case, it’s an optical low pass filter or OLPF that sits over the image sensor ...

An additional advantage of the polynomial correction methods over oversampling is that they do not introduce overshoot beyond the clipping level in the waveform. The proposed techniques are useful in audio and other fields of signal processing where digital signal values must be clipped but aliasing ...
In general, a measurement chain designed for digital signal conditioning consists of several components, such as sensors, cables, amplifiers, data acquisition hardware and software. To acquire analog measured values, an analog-digital converter is required which is integrated into the data acquisition ...
