A seven-segment display decoder is required to produce the following alphanumeric characters depending upon the value of a 3-bit binary input (A B C) according to the following list: The characters will be displayed on the seven-segment displays shown in figure 2: In order to activate or deactivate each of the segments we need a logic output to control each of the segments a-g called Ya-Yg. A segment is switched ON if the output is a logic 1. (b)Compile a truth table using the 3 bit binary input ABC to produce the required logic for the outputs Ya-Yg;(7 marks) (c)Produce a Karnaugh map for each of the outputs Ya-Yg; (d)Use your Karnaugh maps to derive a minimised Boolean logic expression for each of the outputs Ya-Yg.(9 marks)
