Aliasing can occur in signals sampled in time, for instance in digital audio or the stroboscopic effect, and is referred to as temporal aliasing. Aliasing in spatially sampled signals (e.g., moiré patterns in digital …

本词条由 “科普中国”科学百科词条编写与应用工作项目 审核 。 混叠（英语：Aliasing），频率名词，在 信号 频谱上可称作叠频；在 影像 上可称作叠影。 主要来自于对连续时间信号作 取样 以 数字化 …

Alisaing 现象 混叠（Aliasing）是指当信号的采样频率低于其奈奎斯特频率（NyquistFrequency）时，高频信号成分会被错误地映射到低频范围内，从而导致失真。 奈奎斯特频率是信号最高频率的两倍， …

With type aliasing, a short name could be given to this type and thus reduce clutter in the code.

Jul 23, 2025 · The aliasing effect, also known as aliasing distortion or simply aliasing, is a phenomenon that occurs in signal processing, particularly in digital signal processing (DSP), when a continuous …

Aliasing, essentially the signal processing version of identity theft, occurs when each period of the spectrum of the samples does not have the same form as the spectrum of the original signal.

混疊 （英語： Aliasing），在 訊號 頻譜上可稱作 疊頻；在 影像 上可稱作 疊影。 在 統計 、 訊號處理 和相關領域中， 混疊 是指取樣訊號被還原成連續訊號時產生彼此交疊而 失真 的現象。 當混疊發生 …

What is aliasing? Aliasing is the name we give to the phenomenon when two distinct continuous signals x 1 (t) and x 2 (t) produce the same sequence of sample values x [n] when sampled at a fixed rate f s.

Aliasing also makes it difficult for compilers to retain values in registers, as they cannot be certain that the register and memory continue to hold the same values over time. Language features and …

Aliasing is a potential problem whenever an analog signal is point sampled to convert it into a digital signal. It can occur in audio sampling, for example, in converting music to digital form to be stored on …
