Table 2.27
Passive 40dB Stopband Inverse Chebyshev Component Values

Normalized component values for the third-order and fifth-order Inverse
Chebyshev, which I have calculated using Rhodes' equation and the "impedance
synthesis" method, have been modified to give a 3 dB cutoff frequency of 1 rad/s.
These values are given in Tables 2.28 and 2.29.
