Design Specifications A small corporation has 10 shares of stock, and each share entitles its owner to one vo. at a stockholder's meeting. The 10 shares of stock are owned by four people as fllow Mr. W: 1 share Mr. X: 2 shares Mr. Y: 3 shares Mrs. Z: 4 shares Each of these persons has a switch to close when voting yes and to open when voting no for his or her shares It is necessary to design a circuit that displays the total number of shares that vote yes for each measure. Use a seven-segment display and a decoder, as shown in Fig.9.8 to display the required number. If all shares vote no for a measure, the display should be blank. (Note that binary input 15 into the 7447 blanks out all seven segments.) If 10 shares vote yes for a measure, the display should show 0. Otherwise, the display shows a decimal number equal to the number of shares that vote yes. Use four 74151 multiplexers to design the combinational circuit that converts the inputs from the stock owners'switches into the BCD digit for the 7447. Do not use 5 V for logic 1. Use the output of an inverter whose input is grounded
