An anti-aliasing filter is a low-pass filter used before analog-to-digital converters (ADCs) to prevent aliasing, which occurs when high-frequency signals are misrepresented as lower frequencies. This filter effectively attenuates frequency components above the Nyquist frequency, ensuring accurate signal representation. The discussion highlights the importance of implementing an anti-aliasing filter to maintain signal integrity in digital signal processing.
