It discusses the classification of signals as continuous-time or discrete-time, periodic or aperiodic, deterministic or random, energy or power signals. e. 4 Period of sequence 2. M. Early systems used policemen and hand signals, while modern signalling was introduced in England in 1842 using fixed semaphore signals and detonators. , speech signal • Multi Download ppt "Chapter 1.

Standard signals- Step, Ramp, Pulse, Impulse, Real and complex exponentials and Sinusoids_Classification of signals – Continuous time (CT) and Discrete Time (DT) signals, Periodic & Aperiodic signals, Deterministic & Random signals, Energy & Power signals - Classification of systems- CT systems and DT This document discusses digital signal processing and its applications. Proakis and Masoud Salehi, Classification of Signals & Systems Introduction to Signals • A Signal is the function of one or more independent variables that carries some information to represent a physical phenomenon. Examples of Systems – A circuit involving a capacitor can be viewed as a system that transforms the source voltage (signal) to the voltage (signal) across the capacitor – A communication system is generally composed of three sub-systems, the transmitter, the channel and the receiver. causal and non causal system 4. 2 Discrete-time system 2. Lecture 2 ; Introduction to Signals; EE 327 fall 2002. The document provides an introduction to signals and systems. com - id: 416d44-Yzg3M THIS PPT DISCUSSES ABOUT TYPES OF SIGNALS IN ELECTRONICS. FIR systems have impulse responses of finite duration, while IIR systems can have impulse responses that extend to infinity. Fourier analysis is used to represent signals in the frequency domain using techniques like the Fourier series for periodic signals and the Fourier transform for aperiodic signals. – A free PowerPoint PPT presentation (displayed as an HTML5 slide show) on PowerShow. Transfer Function A transfer function represents the relationship between the output signal of a control system and input signal, for all possible input values. Karthik Kumar AP/EEE DEPARTMENT OF ELECTRICAL AND ELECTRONICS ENGINEERING NATIONAL ENGINEERING COLLEGE, K. Signals and Systems. of Credits 04 Department Classification of signals: Energy signal, power signal, deterministic signal, random time and discrete-time signals) PPT/Digital Writing Board (online) 3 3rd week 4 contact hours Vector space, subspace, linear independence, basis and dimension, Inner product, norm 2. 5. System:A system is a set of elements or functional block that are connected together and produces an output in response to an input signal. • One-dimensional signals: function depends on a single variable, e. FOURIER SERIES: Representation of Fourier series, Continuous time periodic signals, Dirichlet’s conditions, Trigonometric Fourier Series, Exponential Fourier Series, Complex Fourier spectrum. Read less This lecture covers the basics of discrete-time signals and systems, including signal classification, elementary signals, system properties, and input-output models. There are four basic types of signals: 1) Continuous in both time and value, 2) Continuous in time but discrete in value, 3) Continuous in value but discrete in time, 4) Discrete in both time and value. ) used to denote continuous-time value quantities. SJSU1 Signals and Systems Linear System Theory EE Lecture Eight Signal 5. • CT signals take on real or complex values as a function of an independent variable that ranges over the real numbers and are denoted as x(t). Discrete-Time Signals • Signal that has a value for only specific points in time • Typically formed by “sampling” a continuous-time signal – Taking the value of the original waveform at specific intervals in time • Function of the sample value, n – Write as x[n] – Often called a sequence • Commonly found in the digital world – ex. A nonlinear system is any system that does not have at least one of these properties. Ch. Systems Viewed as Interconnections of Operations. Balaji Author: BALAJI Created Date: 5/14/2020 11:49:32 PM The document discusses signals and systems. 3) Examples of applications of the standard signals are mentioned such as step signals being used for switching devices on and off, and sinusoidal signals being used to represent any sound signal.
