Introduction In this lab, we are going to design some simple digital logic circuit. In addition, we will try to minimize the logic circuit by using K-map. The designed circuit will be simulated using the OrCAD capture and PSpice 2. 3-bit Excess-4 Logic Design Excess-4 Logic is a very simple circuit that creating a result of A+4 when A is input to the circuit. For example, when 2 is input, 6 will be output. When 5 is input, 9 will be output. For a 3-bit Excess-4 Logic, we are going to have 4-bit output. (a) Based on the description above, construct (fill in) the Truth Table of a 3-bit Excess-4 Logic Circuit. (b) Without using minimization, write down the Boolean expression of the four output bits B3​, B2​, B1​,B0​. (b) Without using minimization, write down the Boolean expression of the four output bits B3​,B2​, B1​, B0​ B3= B2= CCIT4082 Digital Logic and Systems (Spring 2023) B1= BO= (c) Simplify the logic by using 4 K-maps. Write down the simplified expressions of B3​,B2​,B1​,B0​. K-Maps with groupings:
