  A signal is a physical quantity that varies with time, space or any other independent variable by which information can be conveyed. A discrete-time signal is often identified as a sequence of numbers, denoted by x[n], where n is an integer. Signals are broadly classified into continuous and discrete signals. A continuous signal will be denoted by x(t), in which the variable t can represent any physical quantity. A discrete signal will be denoted by x[n], in which the variable n is integer value. The variables t and n are assumed to represent time. Operations on Signals: a. Signal addition  It is implemented in MATLAB by the arithmetic operator “+”. However, the lengths of x1(n) and x2(n) must be the same. y(n) = x1(n) + x2(n) b. Signal multiplication It is implemented in MATLAB by the array operator “*”. To multiply sequences of different lengths we can use the following function y(n) = x1(n) * x2(n) Program: clc; close all ; clear all...

Social media has almost completely changed how many of us communicate and it can be a useful way to stay connected. But is there a point where the obsession with the modern phenomenon goes from harmless fun to an intrusion on your life? If you’re guilty of any of the following then maybe it’s time for you to take a step back from social media 1. Choosing the right status is torturous.  Image: Google Much like deciding on the right selfie, choosing the right thing to say on a status or tweet can be extremely difficult. Usually, the average user’s casual looking status will have gone through rigorous editing, multiple deletions and about 10 re-writes it’s that big of a deal. 2. You closely monitor ‘likes’ Image: Google Social media ‘likes’ mean a lot to the social media savvy. They’re a form of acceptance and after a while getting more and more likes can become quite the addiction. To the selfie addict, there’s no bigger achievement than going into double-figure...

 Ransomware is, without a doubt, one of the biggest threats facing home computer users in years. Unlike many online attacks, it isn’t primarily out to steal your bank details or spy on you. Instead, it wants to scare you into handing over money to the attacker at the other end of the internet. How does it do this? By locking you out of your machine or folders unless a ransom is paid. Failure to do so could result in you being locked out forever.   How does it work? There are two main types of ransomware: 1.‘Lock screen’ ransomware is an older, less common type which locks a user’s screen, often flashing up messages spoofed to appear as if they’ve come from the police. The idea is to scare the victim into paying up. 2.Crypto-ransomware is by far the most common and destructive type. Once it finds its way onto your machine it will encrypt all or most of the data on your hard drive based on file type. This means you won’t be able to make sense of any of i...
