In Boolean or logic algebra, a logic function is a mathematical expression which specifies the relationship between inputs and outputs of a logic circuit. Boolean functions can be classified into two types namely, completely specified logic functions and incompletely specified logic functions. A completely specified logic function is one whose ...

A JK flip flop is a type of 1-bit memory element having inputs namely J and K, one clock input, and two output specified by Q and Q'. The JK flip flop is an improved version of SR flip flop which does not have forbidden state. To avoid the forbidden ... Read More

What is a Decoder? In digital electronics, a decoder is a combinational logic circuit which is capable of converting information in binary form N inputs to a maximum of 2N outputs. The block diagram of a typical decoder is shown in Figure-1. It can be seen that a decoder ... Read More

What is a Decoder Driver IC? A type of integrated circuit (IC) which is designed to decode information specified in the binary form is known as decoder driver IC. A decoder driver IC generates output signals to drive different electronic devices like LEDs, electronic relays, electric motors, etc. Decoder driver ... Read More

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, ...

What is a Decoder? A decoder is a combinational logic circuit that converts an N-bit binary input code into a 2N output lines such that only one output line will be active for each one of the possible combinations of inputs. The block diagram of a decoder is shown in ... Read More

What is S-R Flip-Flop? In digital electronics, the S-R flip-flop is a sequential logic circuit that have two inputs, i.e. S and R, and two outputs, i.e. Q and Q'. The input S represent "Set" and the input R represents "Reset". The output Q is the normal output of the ... Read More

The rate of work done in an electric circuit is known as electric power. In an electric circuit, there are three types of electric powers viz. active power, reactive power and apparent power. 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
