提供了集总元件切比雪夫阻抗变换网络的元件值表，以及给出每种设计的切比雪夫通带纹波的表。这些电路由使用串联电感和并联电容形成的梯形网络组成；它们在任意比率的电阻器终端之间提供切比雪夫阻抗匹配（列出了电阻器终端比从 1.5 到 50 的设计）。这些网络的响应在直流时具有中等高的衰减（衰减量取决于终止比）；然后，它们的衰减在切比雪夫工作频带内降至非常低的水平，然后以低通滤波器的典型方式急剧上升到工作频带之上。给出了工作频带分数带宽范围为 0.2 至 1.0 的设计。这些阻抗变换网络可以在低频应用中以集总元件形式实现，在微波频率下以半集总元件形式（例如波纹波导）实现。
Tables of element values are presented for lumped-element Chebyshev impedance-transforming networks, as are tables giving the Chebyshev passband ripple of each design. These circuits consist of a ladder network formed using series inductances and shunt capacitances; they give a Chebyshev impedance match between resistor terminations of arbitrary ratio (designs with resistor termination ratios from 1.5 to 50 are tabulated). The responses of these networks have moderately high attenuation at dc (the amount of attenuation depends on the termination ratio); their attenuation then falls to a very low level in the Chebyshev operating band, and then rises steeply above the operating band in a manner typical of low-pass filters. Designs having operating-band fractional bandwidths ranging from 0.2 to 1.0 are given. These impedance-transforming networks can be realized in lumped-element form for low-frequency applications, and in semilumped-element form (such as corrugated waveguide) at microwave frequencies.
