CS 194 Lab 07 Introduction to Digital Design Fall 2018 DESIGN AND ANALYZE ADDERSSUBTRACTOR USING MULTSIM Name: Learning Objective: To implement and design an arithmetic circuit that will perform both addition and subtraction. Pre-Lab: WSU Id 1. Draw full adder circuit by using XOR, AND and OR gates instead of a block. 3 Input gates can be used. 2. Draw a block diagram for a single full adder/subtractor moduld. 3. Combine 4 block diagrams to draw a complete 4-bit adder/subtractor circuit. Remember, since binary numbers work from the LSB on the right to the MSB on the left, it makes more sense for the blocks to have inputs on the right side and the outputs on the left
