Pour équilibrer au mieux la charge des composants C21 et C22, il est souhaitable de faire en sorte que les impédances des cinquième et septième liaisons, P5 et P7, soient sensiblement égales entre elles, c'est-à-dire qu'elles ne présentent entre elles qu'un écart relatif au plus égal à 5 % en valeur relative.To best balance the load of the components C21 and C22, it is desirable to ensure that the impedances of the fifth and seventh links, P5 and P7, are substantially equal to each other, that is to say that they do not present between them that a relative difference of at most equal to 5% in relative value.

De même, pour équilibrer au mieux la charge des composants C22 et C23, il est souhaitable de faire en sorte que les impédances des sixième et huitième liaisons, P6 et P8, soient sensiblement égales entre elles, l'équilibrage optimal étant donc obtenu en donnant la même valeur aux impédances des liaisons P5, P6, P7 et P8.Similarly, in order to balance the load of the components C22 and C23 as well as possible, it is desirable to ensure that the impedances of the sixth and eighth links, P6 and P8, are substantially equal to each other, the optimal equilibrium thus being obtained by giving the same value at the impedances of the links P5, P6, P7 and P8.

Comme le montrent les figures 2 et 3, l'embase E est de préférence essentiellement constituée par une carte imprimée supportant les connexions K1 à K5, ainsi que trois prises multiconductrices PM1, PM2, et PM3, dans chacune desquelles est enfiché, de façon amovible, un module correspondant M1, M2, ou M3.As shown by Figures 2 and 3 , the base E is preferably essentially constituted by a printed circuit board supporting the connections K1 to K5, as well as three multicore outlets PM1, PM2, and PM3, in each of which is removably connected a corresponding module M1, M2, or M3.

Comme le montre la figure 2, les liaisons électriques P1 à P9 peuvent alors être constituées par des pistes portées par cette carte imprimée.As shown in figure 2 , the electrical connections P1 to P9 can then be constituted by tracks carried by this printed circuit board.

Cependant, comme le montre la figure 3, les liaisons électriques P1 à P9 peuvent aussi être constituées par des fils conducteurs isolés, par exemple disposés sur la face postérieure de cette carte imprimée.However, as shown in figure 3 the electrical connections P1 to P9 may also be constituted by insulated conductor wires, for example arranged on the rear face of this printed circuit board.
