PROBLEM 2 (7 PTS) Complete the timing diagram (signals DO and DATA) of the following circuit. The circuit in the blue box computes the signed operation T-4, with the result having 5 bits. T is a 4-bit signed (2C) number. For example: if T=1010 DO = 1010 - 0100 = 11010 + 11100 = 10110. = DI DATA 5. DO T-4 T OE OE DATA 1011 0011 0100 1001 DI 0101 0110 1011 11101 1001 DO
