Recall the definitions of signed integer representations from class: sign-magnitude and 2s complement. (a) Give the 2s complement width 6 representation of the number represented in binary fixed-width 6 representation as (001011)2,6. (b) Give the 2s complement width 4 representation of the number represented in sign-magnitude width 4 as [1111]s,4. (c) Give the sign magnitude width 4 representation of the number represented in 2s complement width 4 as [1111]2c,4.
