US 3,939,336 A · Apparatus for analysis of network diagrams

Abstract

An apparatus for analysis of network diagrams, comprising a branch model unit wherein the branch models are connected to one another in accordance with the topology of the network diagram by means of a patch board, and a control unit connected to the branch model unit. Each branch model of said branch model unit includes a time interval forming unit, which time interval corresponds to the length of the respective branch, and an indication unit having three terminals, one of these terminals being connected to the output of the time interval forming unit, the second terminal being connected to the input of the latter, and the third terminal serving as the end point of the respective branch model, the starting point of this branch model being the input of the time interval forming unit. The control unit includes a calendar device, both the calendar device and control subunit being connected to a pulse generator.
