(8) In a seven segment display as shown below, each of the seven segments are activated for various digits. The input is given in Binary Coded Decimal format. (8) (a) Design a combinational circuit to activate the segment B such that the circuit can be realized with NOT-AND-OR as gate levels. Find the boolean function and implement the circuit using a 3 to 8 line decoder. (b) Obtain the minimal POS expression for segment C. Realize the circuit using a suitable multiplexer. E
