Question 1 (25 points]: Consider the following four Boolean functions written in SOP minterms: . f(x,y,z) = m3 + m6 + m7 g(x,y,z) = m0+ m2 + m4 +m6+m7 h(x,y,z) = m0+ ml + m2 + m3 k(x,y,z) = m7 . Write the four functions in the SOP form in terms of x, y, and z. b. Design a circuit with a single decoder and external OR gates
