Cascading of Decoders
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 Figure-1. Here, A, B, C, etc. are the input lines, Y0, Y1, Y2, … etc. are the output lines, and E is the enable input of the decoder. In this article, we will discuss cascading of decoders. Cascading of Decoders means the process of realizing a higher order decoder ...
Read MoreDifference between Active Power and Reactive Power
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 is Active Power? In an AC or DC electric circuit, the amount of electric power which is utilized and consumed in doing a work is called active power. Active power is also known as real power or true power. Active power is usually represented by the letter ‘P’ and is ...
Read MoreDifference between Monochrome and Color Displays
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. ...
Read MoreDifference between LCD TV and Plasma TV
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 MoreDifference between DVI and HDMI
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 MoreMaster Slave Digital Clock
In industries, master-slave digital clock is a digital clock system widely used for precise and coordinated time-keeping. In this article, we will discuss the construction, working, advantages, and applications of the master slave digital clock. Thus, let us start with the basic introduction of the master-slave digital clock. What is a Master-Slave Digital Clock? A type digital clock system which consists of a master-clock and one or more slave-clocks is referred to as a master slave digital clock. The master clock performs a function of sending a timing signal to the slave clocks, so that the slave clocks can ...
Read MoreLockout Condition in Counter
A digital counter is a sequential logic circuit which counts the number of clock pulses or events that occur over time. Now, let us discuss the lockout condition in counter. What is Lockout Condition in Counter? In digital counters, the condition wherein the counter enters to an unused state and rather than coming out of this unused state to a valid state or initial state, it switches to another invalid or unused state and gets stuck up in the cycle of unused states only, is known as the lockout condition in the counter. Therefore, in the case of lockout condition, ...
Read MoreGeneralized Number Systems
What is a Generalized Number System? A mathematic structure which can extend the properties of the conventional number system like integers, real numbers, rational numbers, complex numbers, etc. to a more general case is known as a generalized number system. The major applications of generalized number systems include many areas of mathematics such as algebra, analysis, number theory, topology, etc. In more simple terms, a generalized number system can be defined as the generalization of the conventional/traditional number systems. Importance of Generalized Number Systems Generalized number systems are considered an important part of modern mathematics and science because they provide ...
Read MoreFlip-Flop Used as a Divider Circuit
Let's start this article with a basic overview of flip-flops before moving onto discuss how they can be used as a divider circuit. What is a Flip-Flop? In digital electronics, a flip-flop (FF) is a sequential logic circuit which is used for storing 1-bit of information. As we know, in digital systems, information is represented in binary form, i.e. in terms of 0 and 1. Where, a binary 0 and a binary 1 is referred to as a bit. A flip-flop is a 1-bit memory cell that stores information in terms of 0 or 1. Therefore, flipflop is the fundamental ...
Read MoreEdge-triggered Latches
In digital circuits, a latch is a sequential logic circuit which has two stable states. Hence, a latch is also called as a bistable-multivibrator. A latch has capacity to store 1-bit of information. A latch has one or more inputs and two outputs. The outputs of a latch are specified by Q and Q'. Where, Q is the normal output of the latch and Q' is the inverted output. The block diagram of a latch is shown in Figure-1. In this article, we will discuss about the edge triggered latches, their types, applications. So, let us start with the ...
