Abstract :
IN FILTER DESIGN the determination of expected attenuation may be accomplished by the use of the basic formula for the propagation constant of a ladder-type half-section, P = \\alpha + j \\beta = \\sinh ^{-1} \\sqrt Zr^{\\prime \\underline {\\phi}} , but this necessitates long and tedious calculation. Graphical methods often have been used but the lengthy calculation of \\sqrt Zr^{\\prime \\underline {\\phi}} usually has remained even with dissipation neglected.
