Q1) Assuming that we use 6-bits to represent signed numbers: [10 points] nt binary representation is used, what is the range of values that can be represented? What is the largest number that can be subtracted from (-13) without causing overflow? Calculate 100000-101011 (using 2's complement), indicate if over flow occurs. Calculate 010110 -001111 (using 1's complement), indicate if over flow occurs. Calculate 100110 - 011011 (using signed-magnitude), indicate if over flow occurs. Q2) Using minimum number of the same gate type, design a circuit that has a 4-bit signed number input represented in 2's complement X, that produces an output Y -X-1 (Y is also represented in 2's complement). Verify the correctness of your circuit with Verilog simulations (no delays). 120 points]
