2) A Hexadecimal to 7-segment display controller will be designed. Block diagram of the complete system is shown in Fig. 1. In order to turn on a segment the corresponding control output of the controller is set to logic-1. Fill in the truth table given in Fig. 2. a) The circuits for co and cl will be implemented by using 8-to-1 MUXS and AND, OR, NOT b) gates. Draw the circuits for c0 and cl. c) The circuits for c2 and c will be implemented by using 3-to-8 active 1 output with enable input DECODERS and NOR gates. Draw the circuits for c2 and c6.
