Appendix H 475
Simplified Notations
The equations describing the element values of some of the networks can be
clarified by the use of more simplified notations. This has been done in the
charts by substitution of symbols for some of the more complicated relationships.
These symbols represent the following expressions:
1. The coefficients A, B, D, and E represent various combinations of L
and C. They can be determined from the applicable equations on the
chart.
2. W=A(A-p 2 )/P(AD-PE),
X=(A-P')/(E-PD),
Y = (AD - PE)/(A - p 2 ),
z= P(E-PD)/(A- p 2 ),
where P=(~+ )B 2 -4A )/2.
