  5. Butterworth filter - Wikipedia

    en.wikipedia.org/wiki/Butterworth_filter

    The Butterworth filter is a type of signal processing filter designed to have a frequency response that is as flat as possible in the passband. It is also referred to as a maximally flat magnitude filter. It was first described in 1930 by the British engineer and physicist Stephen Butterworth in his paper entitled "On the Theory of Filter ...

  6. Low-pass filter - Wikipedia

    en.wikipedia.org/wiki/Low-pass_filter

    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 than the cutoff frequency. The exact frequency response of the filter depends on the filter design. The filter is sometimes called a high-cut filter, or treble-cut filter in audio applications.

  7. Band-stop filter - Wikipedia

    en.wikipedia.org/wiki/Band-stop_filter

    In signal processing, a 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. [1] It is the inverse of a band-pass filter. A notch filter is a band-stop filter with a narrow stopband (high Q factor ). Narrow notch filters ( optical) are used in ...
