Question: Make a circuit which gives the absolute value of a 4-bit binary number. Use four full adders, four multiplexers, and four inverters.
Suppose negative numbers are represented in 2's complement. Recall that one way to find the 2's complement of a binary number is to invert all of the bits and then add 1. Describe for 5 stars.
I have the answer already but i do not understand it; I need expert to guide through it step by step. thanks!
