Considering the single section shown in Fig. 2 as the basic building block, 

 the loss and phase may be expressed in the form 



{P + kn - J0in){p -\- kn -\r jOJn) 



? 2 



A+jB 



(p — kn — J0in){p — k„ -\- J03n)

Basic lattice delay section. 



where 



A = insertion loss in nepers 



B = insertion phase in radians 



P = j^ 



CO = frequency in radians per second 



^n,w„ = real positive constants
