Question 2 [15 points] Design a circuit that can convert a 3-bit binary number x( denoted as X2X1%) into it's 2's complement Y (denoted as Y Y Yo). Implement this circuit with a 3x8 decoder. Provide truth table and drawing the logic/circuit diagram. Use the block diagram for the decoder provided in Figure A4 in supplements. Please label the inputs and outputs clearly. Note: use single 3x8 decoder Question 3 (15 points] A priority encoder is an encoder circuit that includes the priority function. The operation of the priority encoder is such that if two or more inputs are equal to 1 at the sameD02 time, the input having the highest priority will take0 precedence. The truth table of a priority encoder is given1 in the following table. Design this priority encoder circuit and draw the circuit diagram. Please clearly label your inputs and output and write down your intermediate steps. Truth Table of a Priority Encoder Inputs Outouts
