DSP

Adaptive filters are the filters that can change its transfer function corresponding to the error feedback so that it can work on noisy environment.ie these type of filters can distinguish the input and the noise and can able to change its transfer...

ATM - Complete Guide

What is ATM? #)ATM(Asynchronous Transfer Mode) is a transfer mode in which information is organized into cells. #)It is asynchronous in the sense that the occurrence of a cell containing information from an individual user is not necessarily...

#)ATM is the underlying message format of B-ISDN. B-ISDN layering has no relationship whatsoever with the OSI reference model. Physical Layer #)The physical layer consists of two sublayers. #)The physical medium (PM) sublayer includes only...

ATM’s POSITION IN THE OSI MODEL

#)ATM standards define protocols that operate at Layer 2 (the data link layer) of the International Standards Organization (ISO) seven-layer Open Systems Interconnection (OSI) reference model. #)The diagram below shows the layered architecture of...

SYNCHRONOUS MOTOR

SYNCHRONOUS MOTOR   INTRODUCTION: Synchronous motors are those that run only at Synchronous speed ie.. constant speed. It is also called as constant speed running motor.   OPERATION: It works on the principle of “MAGNETIC LOCKING”. When...

Electrical devices

Working of a speaker : Speakers easily play the most significant role in enhancing the audio experience.Devices such as speakers and microphones are technically called transducers.A transducer transforms one form of energy into another. A speaker...

Amazing architectures

The power of human imagination has created many wonders in many fields, one such field is architecture.There are many great architectures in the past-the colloseum,pyramids,etc but architects have pushed the limits of architecture to new heights,...

Digital Hardware

Logic circuits are used to build computer hardware, as well as many other types of products. All such products are broadly classified as Digital Hardware. It is derived from the way in which information is represented in computers, as electronic...

FUSE

              Fuse- Defination:                                Fuse is a device which cuts off the circuit when more than predetermined value current flows ina circuit. Fuse wire:                                The current taken by an electric...

Operations Research

The term, operations research was first coined in 1940 by McClosky and Trefthen in a small town Bowdsey, of the U.K. . This new science came into existence in a miliatary context.  During world war II, military management called on scientists from...

Operating System Services

While studying about operating system,its useful to study about the services of an operating system. An operating system provides services to programs and to the users of those programs.The operating system service provides an environment for...

THERMAL BREAKDOWN

Thermal breakdown: This is due to the attainment of an excessive temperature in the dielectric. The electrical energy loss has to be dissipated as heat and if the heat dissipated is less than tha heat generated there is a progressive increase in...

INTRINSIC BREAKDOWN

INTRINSIC BREAKDOWN: In a dielectric, the charge displacement increases with increasing field strength. Beyond a critical value of the field strength, there is an electric breakdown due to the physical deterioration of the dielectric material. The...

DIELECTRIC BREAKDOWN

DIELECTRIC BREAKDOWN: when a dielectric loses its insulation resistance and permits large currents to pass through it, it is said to breakdown. In practical applications, the failure or breakdown of a dielectric material is of great concern to...
