8l design an excess-3 code converter to drive a, Ask an Expert

Engineering

8.L Design an excess-3 code converter to drive a seven-segment indicator. The four inputs (A, B, C,D) to the converter circuit represent an excess-3 digit. Input combinations representing the numbers o through 9 should be displayed as decimal digits. The input combinations 0000, 0001, and 0010 should be interpreted as an error, and an "E" should be displayed.Assume that the input combinations 1101, 1110, and 1111will never occur. Design your circuit using only two-, three-, and four-input NOR gates and inverters.Any solution with 18 or fewer gates and inverters (not counting the four inverters for the inputs) is acceptable.

Use 5 (not b ) for 6. Use g(not q ) for 9.

8.M Design a circuit which displays the letters A through Jon a seven-segment indicator.The circuit has four inputs W,X , Y,Z which represent the last 4 bits of the ASCII code for the letter to be displayed.For example, if l.vXY.Z = 0001, "A" willbe displayed.The letters should be displayed in the following form:
