Question: a. With 7-bit two's complement representation, what is the binary number 1010010 in decimal? b. An unsigned integer is represented by a 3-bit binary number

a. With 7-bit two's complement representation, what is the binary number 1010010 in decimal?

b. An unsigned integer is represented by a 3-bit binary number 1**. We can only see the leftmost bit as 1 but the rightmost 2 bits are hidden. What are the possible decimal values for this unsigned integer? Write down all correct possible values from 0 to 7.

c. Does overflow occur when you add 0101 and 1110, assuming that 4-bit two's complement representation is used? (Yes/NO)
