call back System Corey Johnson Abstract This paper will describes how the peal administration. The main culture to the telephone system is to lay it up so the trunks lines when its a not-ok condition. The methodology utilisation be the K-map and quartette-spot IC and the virtue circuit board. This rise up shows you how to use the pins to strike a not-ok condition for trunks. Introduction ------------------------------------------------- The Telephone system is set up so that if there is a Emergency that the lines are not generous we had to set up, A telephone system between devil cities has three trunk lines A, B and C. during normal operation, trunks B and C lott be employ at the same clock: it doesnt make any dissimilitude if they are used at the same time/ In emergencies, both A and B must be used and C may be used, too. A NOT-OK condition exists when these rules are not satisfied,, so we had to excogitation a truth table for the not- ok condition. u tilize E for emergency it was the MSB (Most material routine) MSB is the bit with the most value, then Trunk A, B, and C., Materials and methods The design we use was the Truth table and K-map, Truth table EX, K-map ex, and so we used a various IC digital/ analog trainer and the four IC (7404, 7400, 7410, 7430) this are NAND and Inverter supply.

Then we set it alone up by put the IC in the trainer. When we did it all the gates was ground and had 5 volts. And was aquiline up to light so it would go off when it was not a OK condition.. The IC Ex how to hook them up,, Results We pendant all the system so the lines would use the rules that were set up for it when lines were existence used. When we had all the I! C hooked up the light should light when we had the same social occasion as the Truth table for the Not-ok condition Discussion We hooked up a Telephone system between carmine cities, using a Truth table, and K-map, so the phone system would not use the NOT-ok Condition, so the lines would work faster.If you want to raise a full essay, order it on our website: OrderEssay.net
