What is a Logic Function? In digital electronics and Boolean algebra, an expression that have some operations performed on the binary inputs to produce an output in the binary form is called a logic function. Logic functions are also called Boolean functions. Depending on the specified output, there are two ... Read More

In digital electronics, a flip-flop is a most fundamental memory element used in several electronic circuit to store 1-bit information. A flip-flop is a basically a bistable multivibrator having two stable states. Flip-flops are made up of a combination of logic gates. However, a logic gate itself cannot store information, ...

In this article, we will discuss the major differences between active power and reactive power. What ... Read More

There are two types of headphones namely, noise-cancelling headphones and noise-isolating headphones, which are designed to suppress the unwanted external noise in the sound. But both are completely different from each other. The main difference between noise-cancelling and noise-isolating headphones is that the noise-cancelling headphones actively reduce external noise ... Read More
