Web17 nov. 2024 · Since the impulse response of an ideal low pass filter extends to plus and minus infinity, the corresponding filter is not causal, i.e., in order to implement it (exactly) you would need to know the complete input signal (including its future) to compute the current output value. Furthermore, the sinc function only decays as 1 / n, which makes ... WebA low pass filter is the basis for most smoothing methods. An image is smoothed by decreasing the disparity between pixel values by averaging nearby pixels. Using a low pass filter tends to retain the low frequency information within an image while reducing the high frequency information.
