Many content filters have an option which allows authorized people to bypass the content filter.

Many scare stories have originated from various Russian gas masks and their filters that are now common in surplus stores ; the GP-5 was often considered to have an asbestos filter, however like most cold-war masks it only contains activated charcoal.

Many digital filters are based on the Fast Fourier transform, a mathematical algorithm that quickly extracts the frequency spectrum of a signal, allowing the spectrum to be manipulated ( such as to create band-pass filters ) before converting the modified spectrum back into a time-series signal.

Many second-order filters are designed to have " peaking " or resonance, causing their frequency response at the cutoff frequency to be above the horizontal line.

Many fundamental DSP algorithms, such as FIR filters or the Fast Fourier transform ( FFT ) depend heavily on multiply – accumulate performance.

Many machines use " spin disc filters ", which remove the muck from the filter by centripetal force while it is back washed with solvent.

Many graphical software products ( e. g. Adobe Photoshop or GIMP ) offer simple motion blur filters.

Many earlier multi-shot backs could natively capture only grayscale images ; color images were created by scanning three times through red, green, and blue filters which rotated into place.

Many municipal systems in the U. S. initially used slow sand filters, but as cities have grown they subsequently installed rapid sand filters, due to increased demand for drinking water.
