Design a combinational circuit with four inputs X3X2X1X and two outputs A and B. X3X2X1 Xo represents a binary number with Xo representing the lowest significant (right most) bit and X3 being the highest (left most) bit. A will be true when the number is -7, -3, and 5, and we do not care when the number is 1 or 7. B will be true when the binary number is -4, -2, or -1. a. Give the reduced algebraic equations for A and B using k-Maps b. Draw the circuit in Digital. The inputs and outputs should be labeled in Digital. You may use multi input and/or gates, however, no bus lines
