An anti-aliasing filter ( AAF) is a filter used before a signal sampler to restrict the bandwidth of a signal to satisfy the Nyquist–Shannon sampling theorem over the band of interest.
24 Mac 2020 · Band limiting is accomplished by using analog low-pass filters that are called anti-aliasing filters. These filters must band limit without adding signal distortion, noise, or amplitude variations with frequency.
1 Jul 2024 · Introduction to Anti-Aliasing Filters. According to the Nyquist sampling theorem, the sampling rate should be at least twice the maximum frequency component of the signal of interest. In other words, the maximum frequency of the input signal should be less than or equal to half of the sampling rate.
Anti-aliasing filter is critical to eliminating aliasing of higher frequencies to lower frequencies when converting analog signals to digital signals. It is therefore placed at the input of an analog to digital (ADC) converter.
22 Mei 2022 · The optimal anti-aliasing filter would be the ideal lowpass filter with cutoff frequency at \(\omega_s/2\), which would ensure that the original signal spectrum and the reconstructed signal spectrum are equal on the interval \((−\omega_s/2,\omega_s/2)\).
17 Mac 2022 · As a special type of low-pass filter, an anti-aliasing filter design helps preserve signal quality at an ADC input. Here’s how an anti-aliasing filter design helps prevent signal distortion during sampling and A/D conversion.
