Signals and Systems is an introduction to analog and digital signal processing, a topic that forms an integral part of engineering systems in many diverse areas, including seismic data processing, communications, speech processing, image processing, defense electronics, consumer electronics, and consumer products.
The course presents and integrates the basic concepts for both continuous-time and discrete-time signals and systems. Signal and system representations are developed for both time and frequency domains. These representations are related through the Fourier transform and its generalizations, which are explored in detail. Filtering and filter design, modulation, and sampling for both analog and digital systems, as well as exposition and demonstration of the basic concepts of feedback systems for both analog and digital systems, are discussed and illustrated.
It's quite different from the older Signals and Systems book, and it builds on the knowledge acquired through that or a similar basic signals and systems text. Some of the topics covered are state-space models, pulse-amplitude modulation, probabilistic models, random processes, estimation and detection.
So if your goal is to get a good basic knowledge of signals and systems, then I'd recommend either the older Signals and Systems text, or one of the many other similar books. Also take a look at the book recommendations on this site.
Topics covered: Course format and overview; Demonstration of a feedback system used to stabilize an inverted pendulum; Demonstration of digital signal processing used to remove distortions and background noise from a musical recording. Mathematical representation of signals and systems.
\(x[3n]\) can be obtained by downsampling \(x[n]\) with a factor \(3\). Noticethat downsampling discrete-time signal is different with compressingcontinuous-time signal because discrete-time signal only have integers asindependent variables.
Determine which of these properities hold and which do not hold for each ofthe following continuous-time systems. Justify your answers. In eachexample, \(y(t)\) denotes the system output and \(x(t)\) is the systeminput.
Time invariant: A system is time invariant if the behavior and characteristicsof the system are fixed over time. Time invariance can be justified very simply.A system is time invariant if a time shift in the input signal results in anidentical time shift in the output signal.
Determine which of the properties listed in Problem 1.27 hold and which donot hold for each of the following discrete-time systems. Justify youranswers. In each example, \(y[n]\) denotes the system output and \(x[n]\) isthe system input.
In the text, we discussed the fact that the property of linearity for asystem is equivalent to the system possessing both the additive propertyand homogeneity property. Determine whether each of the systems definedbelow is additive and/or homogeneous. Justify your answers by providing aproof for each property if it holds or a counterexample if it does not.
A system is invertible if distinct inputs lead to distinct outputs. There existsan inverse system for an invertible system so that when cascaded with theoriginal system, the output will be equal to the input to the original system.
Then, we have \(x[n] = y[n] - \frac12\sum_k=-\infty^n-1 ( \frac12)^n-1-k x[k] = y[n] - \frac12 y[n-1] \) So the inverse system is \( y[n]=x[n] - \frac12 x[n-1] \) So the inverse system is \( y[n]= x[n] - \frac12 x[n-1] \).
The system is not invertible. Notice this system is different with system\(\mathbf(l)\) which is continuous-time system. \(x[2n]\) is a downsampling of\(x[n]\). So there are tons of signals as \(x[n]\) which can be downsampling toget \(x[2n]\).
In this problem, we illustrate one of the most important consequences of theproperties of linearity and time invariance. Specifically, once we know theresponse of a linear system or a linear time-invariant (LTI) system to asingle input or the response to several inputs, we can directly compute theresponse to many other input signals. Much of the remainder of this bookdeals with a thorough exploitation of this fact in order to develop resultsand techniques for analyzing and synthesizing LTI systems.
Signals & Systems is a branch of engineering and applied mathematics that deals with the analysis and processing of signals, which are mathematical representations of physical quantities that carry information. It also involves the study of systems, which are mathematical models that describe the relationship between inputs and outputs of a physical system.
Alan V. Oppenheim is a professor of engineering at the Massachusetts Institute of Technology (MIT) and a pioneer in the field of Signals & Systems. He co-authored the textbook "Signals & Systems" with his colleague, Alan S. Willsky, which has become a widely used reference in the field.
The latest edition of "Signals & Systems" by Alan V. Oppenheim is the 2nd edition, which was published in 1996. It is commonly referred to as the Oppenheim and Willsky textbook and is still widely used in undergraduate and graduate courses on Signals & Systems.
The key topics covered in "Signals & Systems" include signal classification and properties, Fourier series and transforms, Laplace transforms, z-transforms, sampling and reconstruction of signals, and filter design. It also covers the analysis of continuous-time and discrete-time systems and the relationship between input and output signals.
"Signals & Systems" by Alan V. Oppenheim provides a strong foundation in the theory and principles of signal processing and system analysis, which are essential in many practical applications. This knowledge can be applied in fields such as telecommunications, digital signal processing, control systems, and biomedical engineering, among others.

This comprehensive exploration of signals and systems develops continuous-time and discrete-time concepts/methods in parallel -- highlighting the similarities and differences -- and features introductory treatments of the applications of these basic methods in such areas as filtering, communication, sampling, discrete-time processing of continuous-time signals, and feedback. Relatively self-contained, the text assumes no prior experience with system analysis, convolution, Fourier analysis, or Laplace and z-transforms.
Signals, Systems and Inference is a comprehensive text that builds on introductory courses in time- and frequency-domain analysis of signals and systems, and in probability. Directed primarily to upper-level undergraduates and beginning graduate students in engineering and applied science branches, this new textbook pioneers a novel course of study. Instead of the usual leap from broad introductory subjects to highly specialised advanced subjects, this engaging and inclusive text creates a study track for a transitional course.
Properties and representations of deterministic signals and systems are reviewed and elaborated on, including group delay and the structure and behavior of state-space models. The text also introduces and interprets correlation functions and power spectral densities for describing and processing random signals. Application contexts include pulse amplitude modulation, observer-based feedback control, optimum linear filters for minimum mean-square-error estimation, and matched filtering for signal detection. Model-based approaches to inference are emphasised, in particular for state estimation, signal estimation, and signal detection.
Join instructors @Leila Fuladi and @Mariusz Jankowski and a cohort of fellow learners to study the concepts, mathematics, principles and techniques of signal processing. We'll cover methods of analysis for both continuous-time and discrete-time signals and systems, sampling and introductory filter design. The concepts and methods of signals and systems play an important role in many areas of science and engineering and many everyday signal processing examples are included. A basic working knowledge of the Wolfram Language is recommended.
Hi, I have a few questions about the quiz:Quiz3 Q10 in my framework, I think x[n] should be delta[n]-delta[n-1]+2delta[n-3], then I got the correct answer, otherwise, even the length of convolve won't match...
The missing L31 course video is a known issue that we expect to resolve by next week. I want to remind our Daily Study Group participants that logging watched videos in the course is NOT a requirement for your completion certificate. As a Study Group participant, you need only to pass the course quizzes.
Quiz 8 has been released as part of the course framework made available to our Study Group participants. Please check your recording notification email sent today and upcoming reminder emails for your link to the pre-released course framework.
