Minterms and maxterms are fundamental concepts in Boolean algebra used to define functions. Minterms represent the sum of products, where each term is an AND operation of variables that results in the function being true. Conversely, maxterms represent the product of sums, where each term is an OR operation of variables that results in the function being false. The discussion emphasizes that the definitions can be found in the provided material, which includes examples to clarify these concepts. Understanding these definitions is crucial for working with Boolean expressions effectively.

i couldn't find the definition of Minterms and maxterms of boolean's expression on the internet nor my book. Can someone explain it? I was given only this in my book, without any explanation.

The two definitions are right there in the photo you posted 2.3.1

Try reading it again and look at the examples provided.

The first f(x,y,z) adds up a bunch of Boolean terms. Each term is composed of factors of x,y and z. X,y and z can have values of 0 or 1 so each term is an AND of x,y and z. The adding is in reality the OR operation.

The equation is saying f(x,y,z) is true when xyz is true OR x'yz is true OR ... That's a minterm way of defining the f function.

The alternate way to define the f function is to use a product of factors with each factor being an OR of x, y, z inputs.
 

Thread 'Electric power distribution from powerplant to homes'

I am trying to understand how transferring electric from the powerplant to my house is more effective using high voltage. The suggested explanation that the current is equal to the power supply divided by the voltage, and hence higher voltage leads to lower current and as a result to a lower power loss on the conductives is very confusing me. I know that the current is determined by the voltage and the resistance, and not by a power capability - which defines a limit to the allowable...
