切比雪夫型滤波器以帕夫努特·切比雪夫的名字命名，因为它们的数学特性来自切比雪夫多项式。
PI滤波器是一种具有串联元件和两个并联元件的滤波器，其连接形状为希腊字母PI。
切比雪夫滤波器是模拟或数字滤波器，与巴特沃斯滤波器相比，具有更陡峭的滚降和更多的通带波纹或阻带波纹。切比雪夫滤波器具有在滤波器范围内最小化理想滤波器特性与实际滤波器特性之间误差的特性，但通带中存在波纹。
切比雪夫滤波器在-3db点以外提供更陡峭的衰减率。切比雪夫滤波器比巴特沃思滤波器对元件容差更敏感。
对于偶数阶滤波器，所有纹波都高于直流归一化通带增益响应，因此截止频率为0 dB。对于奇数阶滤波器，所有纹波都低于直流归一化通带增益响应，因此截止频率为-(纹波) dB。
高通滤波器是一种通过高频但衰减低于截止频率的频率的滤波器。
The Chebyshev type filter is named in honor of Pafnuty Chebyshev because their mathematical characteristics are derived from Chebyshev polynomials.
A PI filter is a filter that has a series element and two parallel elements connected in the shape of the Greek letter PI.
Chebyshev filters are analog or digital filters having a steeper roll-off and more passband ripple or stopband ripple than Butterworth filters. Chebyshev filters have the property that they minimize the error between the idealized filter characteristic and the actual over the range of the filter, but with ripples in the passband.
Chebyshev filters provide sharper rate of attenuation beyond the -3 db point. Chebyshev filters are more sensitive to component tolerances than Butterworth filters.
For even-order filters, all ripple is above the dc-normalized passband gain response, so cutoff is at 0 dB. For odd-order filters, all ripple is below the dc-normalized passband gain response, so cutoff is at -(ripple) dB.
A High pass filter is a filter that passes high frequencies, but attenuates frequencies lower than the cutoff frequency.
