8E
Use h (not ) for 6. Use 4 (not 4 ) for 9. Any solution that uses 18 or fewer gates and inverters (not counting the four invert- ers for the inputs) is acceptable. 8.E Design a circuit which multiplies two 2-bit binary numbers and displays the answer in decimal on a seven-segment indicator. In Figure 8-14, A and B are two bits of a binary number N1, and C and D are two bits of a binary number N2. The product (N, × N,) is to be displayed in decimal by lighting appropriate segments of the seven-segment indicator. For example, if A = 1, B = 0, C = 1, and D = 0, the num- ber “4" is displayed by lighting segments 2, 3, 6, and 7. Use h (not h) for 6. Use 9 1 4 (not 4) for 9. Design your circuit using only two-, three-, and four-input NAND gates and invert- ers. Try to minimize the number of gates required. The variables A, B, C, and D will be available from toggle switches. Any solution that uses 18 or fewer gates and inverters (not counting the four inverters for the inputs) is acceptable. For the following question, I modified the number of inputs to be 4 rather than 5 so yo Emaps) 8.N A simple security system for two doors consists of a card reader and a keypad.
