Cover: A switching function f(x (x1,x ,x2,…,xn) ) is said to<br />
cover another function g(x (x1,x ,x2,…,xn), ), if f assumes the<br />
value 1 whenever g does.<br />
<strong>Implicant</strong> : Given a function F of n variables, a<br />
product term P is an implicant of F iff for every<br />
combination of values of the n variables for which<br />
P=1 , F is also equal 1.That is, P=1 implies F=1. F=1<br />
