Abstract

The interface circuit is assembled from a number of preselected integrated circuit hybrid circuits, or discrete components chosen in dependence of the required functional characteristics. The components are mounted on a common circuit board. The latter is formed with metallised circuit paths, for interconnecting the circuit elements and for allowing them to be connected to external conductors etc., pref. with the circuit paths formed on the opposite surface of the circuit board to that on which the circuit elements are mounted.
