antialiasingfiltar
Antialiasingfiltar is a term used to denote an anti-aliasing filtering stage in digital signal processing. The more standard spelling is anti-aliasing filter, and antialiasingfiltar is often a misspelling or nonstandard label for the same concept. The purpose of such a filter is to suppress high-frequency content that would alias when a signal is sampled or when a signal or image is downsampled or resampled.
Principle and implementations. In general, an antialiasingfiltar is a low-pass filter designed to limit the signal
Variants and trade-offs. Common designs include windowed sinc FIR approximations and various IIR choices such as
Applications. Antialiasing filters are used in audio resampling, image and video processing, digital photography, and computer
