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...

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

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

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...

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

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

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...

although the Gaussian has lower time delay and zero overshoot. A Bessel low-pass filter is characterized by its transfer function: H ( s ) = θ n ( 0 ) θ n...

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...

band-pass filter, band-stop filter, low-pass filter or high-pass filter. The tuning application, for instance, is an example of band-pass filtering. The...

bandlimited (specifically, not having high frequencies) or passed through a low-pass filter; this is the frequency domain description. In terms of the time domain...

components. A low-pass filter passes low-frequency components of signals while attenuating higher frequencies. Some audiophiles use a low-pass filter in the...

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...

filter depends on the filter design. The filter is sometimes called a high-cut filter, or treble-cut filter in audio applications. A low-pass filter is...

high-pass filter passes high frequencies. A band-pass filter passes a band (range) of frequencies. A band-stop filter passes high and low frequencies...

Optical filters selectively transmit light in a particular range of wavelengths, that is, colours, while absorbing the remainder. They can usually pass long...

Butterworth squared filter. A Linkwitz–Riley "L-R" crossover consists of a parallel combination of a low-pass and a high-pass L-R filter. The filters are usually...
