[Also in Division H1] The input terminals 11 and 12 of a pulse generator are connected, respectively, to the output from a diode matrix and to a synchronizing voltage, the collector of transistor 13 drawing current, when both input terminals are activated, thereby activating the thyristor 14 and causing the capacitor 15, which is charged through resistor 16, to discharge over the primary winding 17 of the transformer T. The pulse from the output winding 18 is applied to an arrangement for providing illuminated digit shapes (see Division H1). |
