A Committee is composed of a Chairman (C), a Senior member (S), and Member (M). The rules of the committee state that:
i. The vote of the member (M) will be counted as 1 vote.
ii. The vote of the senior member (S) will be counted as 3 votes.
iii. The vote the Chairman (C) will be counted as 4 votes.
Each of these persons has a switch to close (“I”) when voting “YES” and to open (“0”) when voting “NO”. It is necessary to design a circuit that displays the total number of votes for each issue. Use a Seven-segment display and a decoder to display the required number. If all members vote “NO” for an issue, the display should be blank. (Recall that a binary input 15 into 7446 blanks all seven segments). If all members vote “YES” for an issue, the display should be (“0”). Otherwise, the display shows a decimal number equal to the number of “YES” votes. Use two 74153 units, which include four multiplexers to design the combinational circuit that converts the inputs from the members’ switch to the BCD digit for the 7446.
In Logic Works use +5 V for Logic (“I”) and ground for Logic (“0”) and use switches for C, S, and M. Use two chips 74153 and one decoder 7446 verify your design and get a copy of your circuit with the pin numbers to Lab so that you could correct the hardware in exactly the same way.
