Design (schematic) a circuit (as shown below) to calculate the function f = -x + 2.25. You must implement this circuit using only full adders and inverter (NOT) gates (you must use as few as possible). X + 2.25 + The circuit has one input, x = X2X1 Xo, a 3-bit signed integer using 2's complement representation. The output is an n-bit signed fixed-point number, z = 2n-1 ... Zm-1 ... 2120, where Zm-1 ... 212, are the fractional bits. Determine the minimum value of n and m for your implementation. Finally, show the critical path of your design and determine the length (number of gates) of the critical path (draw a separate circuit to showing the critical path).
