What is SR Flip-Flop? SR flip-flop is a simple 1-bit storage element which has two inputs namely S and R, and two outputs, i.e. Q and Q'. Where, S specifies Set input and R specifies Reset input. The output Q is the normal output and the Q' is the complemented or inverted output. In addition to SR inputs, the SR flip flop also has a clock input which is used for triggering the circuit. The block diagram of SR flip flop is shown in Figure-1 below. The operation of the SR flip flop can be analyzed using its truth ... Read More

What is a JK Flip-Flop? JK flip flop is also a 1-bit storage device having two inputs similar to SR flip flop, but it has inputs denoted by J and K instead of S and R. It has two outputs viz. Q (normal output) and Q' (inverted output). The clock signal is used for synchronization of the circuit. The block diagram of the JK flip flop is shown in Figure-1 below. The operation of the JK flip flop can be understood with the help of its truth table which is given below − Inputs Output ... Read More

In digital electronics, a binary counter is a type of sequential logic circuit which is able to count in binary numbers. A binary counter can counter from 0 to 2(n-1), where n is the total number of bits in the counter. Basically, a binary counter is a type of digital circuit which counts the number of clock pulses that occur over a time period. The binary counters are built up of flip flops, where a flip flop is a most elementary memory element that can store 1-bit of information. In a binary counter, each flip flop represents one bit of ... Read More

Display is the most important part of a visual display unit (VDU) like TV, monitor, etc. Depending on the colors displayed on the screen, displays are of two types namely, monochrome display and color display. The fundamental difference between monochrome and color display is that a monochrome display can display graphics like images, text, etc. in gray shades only, while a color display can display graphics in full color. In this article, we will discuss all the important differences between monochrome display and color display. But before discussing the differences, let us first have a look into their basics. ...

TV, Television, is a well-known electronic device used to display audio-video content on a screen. Based on display technology used, several types of TVs available, such as LCD TVs, LED TVs, Plasma TVs, CRT TVs, etc. In this article, we will discuss the important differences between LED TV and Plasma TV. But before that let us first have a look into the basics of LED TV and Plasma TV individually. What is LED TV? A type of TV in which LEDs (Light Emitting Diodes) are used to illuminate the display screen is called LED TV. LED TV is basically ... Read More

TV, Television, is a very common electronic device used to display audio-video content on a screen. Based on the display technology used, several types of TVs available, such as LCD TVs, LED TVs, Plasma TVs, CRT TVs, etc. In this article, we will discuss the important differences between LCD TV and Plasma TV. But, before going to discuss the differences, let us first have a look into the basics of LCD TV and Plasma TV individually. What is LCD TV? LCD stands for Liquid Crystal Display. A type of television in which liquid crystal display technology is used for ... Read More

There are two types of digital video interfaces namely, DVI (Digital Visual Interface) and HDMI (High-Definition Multimedia Interface) that are used for transmitting digital video signals from source devices to a display device like TV, monitor, projector, etc. The most fundamental difference between DVI and HDMI is that DVI (Digital Visual Interface) can transmit only video signals, while HDMI (High-Definition Multimedia Interface) can transmit both video and audio signals. In this article, we will discuss all the important differences between DVI and HDMI interfaces. But before that let us first discuss a bit about DVI and HDMI individually. What ... Read More

Read this article to learn how you can implement a two-variable Boolean function using a 4:1 multiplexer. Let's start with a brief introduction of two-variable Boolean functions and multiplexers. What is a Two-Variable Boolean Function? A two variable Boolean function is a logical expression which has two input variables. Where, each variable can take either a binary 0 or a binary 1 as its value. A two variable Boolean function can have 4 possible combinations of variables, i.e. in SOP form, $\bar{A}\bar{B}, \bar{A} B, A \bar{B}, AB, $ with minterm designations m0, m1, m2, and m3. In POS form, $(A+B), ... Read More

Karnaugh Map (K-Map) K-Map is a graphical tool used for simplifying Boolean expressions represented in their standard form to obtain their minimal form. The K-Map is basically a graph or chart that composed of an arrangement of adjacent cells or squares, where each cell represents a particular combination of variables of the function either in sum or product form. The number of cells in the K-Map depends upon number of variables in the Boolean function, i.e., K-map has 2n adjacent cells, where n is the number of variables in the Boolean expression. Therefore, the number of cells in a 2 ... Read More

A multiplexer or MUX is a combinational circuit that accepts several data inputs and allows only one of them to flow through the output line. Multiplexer (MUX) is also known as data selector because it selects one from many. A MUX consists of 2n data input lines, n select lines, and 1 output line. Since, it converts 2n input lines into 1 output line. Therefore, it is also called many-to-one device. Depending upon the number of input lines, there are several types of multiplexer present such as 2:1 MUX, 4:1 MUX, 8:1 MUX, etc. As this article is primarily meant ... Read More
