  • Aliasing - Wikipedia
    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 images) is referred to as spatial aliasing
  • Aliasing 混叠现象 - 知乎
    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，即： f_s > 2 * f_ {max} fs : 采样频率 fmax : 被采样信号的最大频率
  • aliasing_百度百科
    aliasing是英语中的动词和名词，发音为英 [ˈeɪlɪəsɪŋ]、美 [ˈeliəsɪŋ; ˈeljəsɪŋ]，主要应用于信号处理与计算机图形学领域。 作为动词时意为错误识别信号频率；作为名词指信号采样中因频率不足导致的混叠失真，或计算机图像边缘的锯齿现象。
  • ALIASING中文 (简体)翻译：剑桥词典 - Cambridge Dictionary
    With type aliasing, a short name could be given to this type and thus reduce clutter in the code
  • Aliasing Effect - GeeksforGeeks
    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 signal is sampled at a frequency that is too low to accurately represent the original signal
  • 混叠 - 维基百科，自由的百科全书
    混叠 （英语： Aliasing），在 信号 频谱上可称作 叠频；在 影像 上可称作 叠影。 在 统计 、 信号处理 和相关领域中， 混叠 是指取样信号被还原成连续信号时产生彼此交叠而 失真 的现象。 当混叠发生时，原始信号无法从取样信号还原。
  • Lecture 6: Sampling and Aliasing - University of Illinois Urbana-Champaign
    Aliased Frequency Aliasing comes from two sources: cos( ) = cos(2 n ) cos( ) = cos( 2 n) The equations above are true for any integer n
  • Sampling_and_Aliasing
    Information is generally lost in such discretization processes Today we discussed two mechanisms that can alter the information con-tained in a signal: aliasing and quantization Next time, we will develop representations that are specialized for discrete-time signals
  • 2. 2. Aliasing — Digital Signals Theory - Brian McFee
    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
  • 10. 5: Aliasing Phenomena - Engineering LibreTexts
    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
