PROBLEM #1 A 7-segment display is a common display device having 7 light segments that can be lit in different patterns to represent numbers and some letters. Each segment is assigned to a particular label: a, b, c, d, e, f, or g (as shown in figure to the right). To display a particular number or letter, each of these segments is either "on" or "off". Assume a "1" turns 'on' the corresponding segment and a "0" turns 'off' the corresponding segment. Problem description: You, as part of a team, have been hired by ACME University to design a display that reminds the departmental staff of the fiscal year by displaying the semester name and the last two digits of year. This semester, the message should read "FL2024" using 7- segment displays. Since only certain letters and numbers are relevant, the design team has decided to use a 3-bit CODE for each of the distinct characters needed for the SPR24 message. The encoding shown in the figure below. (Specifically, "000" will be used to represent the letter "F," "001" will be used to represent the letter "L," "010" represents the "2," "011" represents the number "0," and "100" represents the number "4.") Your part of the design is to design an interface (circuit) that takes the 3-bit CODE as input, and generates, as output, the correct bit value for each of the 7-segment display segments, a through g. C: f: FL 2024 JILLI 000 001 010 011 100 g: Vz 01 x 10 Vz 00 10 x Use the figure above to match the desired 7-segment display pattern for each unique character to the corresponding code and complete the function table entries to light up the segments to be displayed. NOTE: you must use don't cares (X) for those input combinations (values of xyz) that are not being used in your design. CODE xyz a b с d e f g 000 001 010 011 100 101 110 111 PROBLEM #2 Function Q is given by the following equation: Q(A, B, C, D, E) = Em(10,11,15,16,26,27,28,31) + Ed(0,3,12,19,20,30) 2.1 Use Quine-McCluskey method to obtain a minimized SOP equation for Q. Ensure the procedure by supplying results of these steps: a) Obtain the resulting Pls b) Clearly mark the EPIs on the PI chart c) Clearly mark any PI chosen for your final answer 2.2 Is the solution unique? 2.3 If solution is not unique, how many minimal SOP equations exist for this problem? Use K-maps to obtain a minimized equation for each output of your interface: a: Vz 00 01 x b: Vz 01 11
