A low-pass filter is a filter that passes signals with a frequency lower than a selected cutoff frequency and attenuates signals with frequencies higher...

the filter design. A high-pass filter is usually modeled as a linear time-invariant system. It is sometimes called a low-cut filter or bass-cut filter in...

contrasts with a high-pass filter, which allows through components with frequencies above a specific frequency, and a low-pass filter, which allows through...

An all-pass filter is a signal processing filter that passes all frequencies equally in gain, but changes the phase relationship among various frequencies...

digital cameras, the anti-aliasing filter is also known as an optical low-pass filter (OLPF), blur filter, or AA filter. The mathematics of sampling in two...

inductor, then the filter presents less attenuation to high-frequency signals than low-frequency signals and therefore is a high-pass filter. Resistors on...

filters generated substantial ripple in the passband, and the choice of component values was highly interactive. Butterworth showed that a low-pass filter...

band-stop filter or band-rejection filter is a filter that passes most frequencies unaltered, but attenuates those in a specific range to very low levels...

high-frequency components; a Gaussian blur is thus a low-pass filter. The Gaussian blur is a type of image-blurring filter that uses a Gaussian function (which also...

A DSL filter (also DSL splitter or microfilter) is an analog low-pass filter installed between analog devices (such as telephones or analog modems) and...
