xpress the negative value - 22 as a 2's complement integer, using eight bits. Repeat it for 16 bits and 32 bits. What does this illustrate with respect to the properties of sign extension as they pertain to 2's complement representation?  8 bit The 8-bit binary representation of 22 is 00010110. So, - 22 in 2's complement form is (NOT (00010110) + 1) = (11101001 + 1) = 11101010
