12. Given the following factored equation that satisfies a fan-in of 2 requirement. f(v, w, x, y.z)-z((v w)(x y)) v+t) First draw a circuit using AND, OR, and INVERTER gates. Then convert this to a NOR only circuit using the method described in section 8.1.3. (multilevel NOR synthesis). Redraw the circuit. 12.
