Question

Design a circuit that displays the letters A through J on 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 WXYZ =
0001, "A" will be displayed.

Construct the circuit as shown below. Apply the 4-bit BCD digits through four switches and observe the decimal from 0 to 9. Input 1010 through 1111 have no meaning in BCD depending on the decoder, These values may cause either a black or a meaningless pattern of the six unused input conditions. ee- 5v 16 Vee 13 1 a 13 12 b 11 CA 10 10 d C 7447 9 e 7 e 13 D 14 11 GND 7730 18 Figure 2-3.
