Design (schematic) a circuit (as shown below) to calculate the function f=(3/4)x +2.25.

you must implement this circuit using only full adders and inverter (NOT) gates (you must use as few as

possible).

The circuit has one input, =x210, a 3-bit signed integer using 2s complement representation. The output is an n-bit signed fixed-point number, = (n-1)...z(m-1)...z1z01 where (1) ... 10 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).
