WebWhat are linear filters? A linear filter F transforms an input signal x = ( x n) to an output signal y = ( y n). This transformation is linear—the transformation of the sum of two signals is the sum of the transformed signals: F ( x + y) = F ( x) + F ( y). Web12 mei 2024 · A filter is a circuit that removes, or “filters out,” a specified range of frequency components. In other words, it separates the signal’s spectrum into frequency components that will be passed and frequency components that will be blocked.
