Question

a) Build the combinational logic circuit of the BCD to 7-segment decoder using LogiSim software as shown below. Take note of the position/location of the inputs and outputs of the circuit. Save the file as "7Segment Decoder". w x y z 88 A = w + xz + xy'z' B = x'z + xy'z' C = x'y' + x'y + xy' D = x'y' + x'y + xy E = x'z' + y' F = w + x'y' + y'z' G = w + y'z' + xy H = xy + xz I = xy + xz J = w + x'y' + y'z' K = w + x'y' + y'z' L = w + x'y' + y'z' M = w + x'y' + y'z' N = w + x'y' + y'z' O = w + x'y' + y'z' P = w + x'y' + y'z' Q = w + x'y' + y'z' R = w + x'y' + y'z' S = w + x'y' + y'z' T = w + x'y' + y'z' U = w + x'y' + y'z' V = w + x'y' + y'z' W = w + x'y' + y'z' X = w + x'y' + y'z' Y = w + x'y' + y'z' Z = w + x'y' + y'z' b) On the Property window of the main circuit, change the ff. information: Circuit name: 7-Segment Decoder Shared label: 7s Decoder On the Project menu of LogiSim, create a new circuit called "Task 2". From the task 2 design layout, add the new 7-segment decoder icon that you created earlier, 7-segment display, and input lines to test the circuit you created as shown below. Show a demo to your instructor for credit. 7s decoder
