Webb10 aug. 2024 · The low pass filters preserves the lowest frequencies (that are below a threshold) which means it blurs the edges and removes speckle noise from the image in the spatial domain. The high pass filter preserves high frequencies which means it preserves edges.

There's also the linear phase filters, which have a symmetrical impulse response, and the minimum phase ones, which have no pre ringing. The linear filters have no group delay (all frequencies have the same delay), so that is considered good. how do i pay my hsbc credit card online

"Webb25 aug. 2024 · A: Q is the “quality factor.”. For a bandpass or notch filter, Q represents the ratio between the center frequency and the 3-dB bandwidth; a higher-Q filter has a narrower, sharper response graph. Q is determined by both the filter design in theory and the real-world, non-ideal performance of its components. The next part of this article ... " - Sharp low pass filter digital
