Combine terms by using Do this repeatedly to eliminates as many literals as possible. A given term may be used more than once because 2. Eliminate redundant terms by using the consensus theorems.
Subsequently, one may also ask, what are the switching function?
A switching function is a function of variables which take only the values 0 and 1, and which takes only these values itself. There are 256 different switching functions of three variables, but only 218 of these really depend on all three variables.
Similarly, how can we minimize the switching function? Reduce the number of product terms to reduce gate count. Minimize the number of literals in each product terms to minimize the number of gate inputs. Simplified switching function has 3 literals and 2 product terms (CD, B) and 3 variables.
Just so, why is the minimization of switching function required?
The minimization of switching functions is important to reduce the original number of logic gates required to implement digital logic circuits. Quine-McCluskey algorithm is classical method for simplifying these functions which can handle any number of variables.

19.1 Circuit SwitchingCircuit switching refers to the mechanism of communications in which a dedicated path with allocated bandwidth is set up on an on-demand basis before the actual communication can take place. On-demand means that the path is set up quickly when the request is made.
How are switching expressions formed?
In Boolean Algebra terms, this expression is that of the OR function which is denoted by a addition or plus sign, (+) between the variables giving us the Boolean expression of: L = A+B.Why are digital circuits called switching circuits?
Digital logic circuits are often known as switching circuits, because in digital circuits the voltage levels are assumed to be switched from one value to another value instantaneously. These circuits are termed as logic circuits, as their operation obeys a definite set of logic rules.How do you solve tabulation method?
