Theso oxprossions incliocte thct complete inversion ti oa place in figuro
lb, whereas in figure".lo inversion is offeoted only relative to parts,
~'2 , of the circuit within those pnrts tho elements of the circuit are not
inverted,
pox com,1ote inversion the circuit in figure 2a is converted into the
circuit in figno 2b, and for partio,1 inversion, corresponding to figurc 1if,
it takes the form represented in figure 2c, Transformation of the circuit in
figure 2a into the circuit in figure 2c will obviously be permissible only if
the contact circuits dctin on thin element have one rend the same form,
The ctructurnl formula of the ciraUit in figure 2a is as follows:
'=P'1 (f'ZX+fl) +'2F2 :1:2 ~"if'iX+ ''lfi+ p'21'2 ? (1t)
The circuit of oloment X will be closod when the contact circuits
connected in series with X axe cidsed ctnd the circuits connected in para-
llel with X are disconrnectod. Thorefore we haves
