This course provides the basic toolkit for any signal processing application - the abstraction of signals and systems, from the point of view of analysis and characterization. ↓ More info below. ↓ Take this course free on edX: https://www.edx.org/course/signals-systems-part-1-iitbombayx-ee210-1x-1#! ABOUT THIS COURSE We encounter signals and systems extensively in our day-to-day lives, from making a phone call, listening to a song, editing photos, manipulating audio files, using speech recognition softwares like Siri and Google now, to taking EEGs, ECGs and X-Ray images. Each of these involves gathering, storing, transmitting and processing information from the physical world. This course will equip you to deal with these tasks efficiently by learning the basic mathematical framework of signals and systems. This course is divided into two parts. In the first part (EE210.1x), we explore the various properties of signals and systems, characterization of Linear Shift Invariant Systems, convolution and Fourier Transform. Building on that, in the 2nd part (EE210.2x) we will deal with the Sampling theorem, Z-Transform, discrete Fourier transform and Laplace transform. The contents of the first part are prerequisites for doing this part. Ideas introduced in this course will be useful in understanding further electrical engineering courses which deal with control systems, communication systems, power systems, digital signal processing, statistical signal analysis and digital message transmission. The concepts taught in this course are also useful to students of other disciplines like mechanical, chemical, aerospace and other branches of engineering and science. What you'll learn - How to unite abstractions for several kinds of systems, to draw a common system description - How to identify properties that this system has or does not have - How to deal with an important class of systems namely, linear shift invariant systems - How to represent and analyze signals and systems in the Fourier domain

COMMUNICATION SYSTEMS: BANDWIDTH OF SIGNAL: In a communication system, the message signal can be voice, music, picture or computer data. Each of these signals has different ranges of frequencies. The type of communication system needed for a given signal depends on the band of frequencies which is considered essential for the communication process. For speech signals, frequency range 300 Hz to 3100 Hz is considered adequate. Therefore speech signal requires a bandwidth of 2800 Hz 3100 hertz – 300 hertz for commercial telephonic communication. To transmit music, an approximate bandwidth of 20 kHz is required because of the high frequencies produced by the musical instruments. The audible range of frequencies extends from 20 Hz to 20 kHz. Video signals for transmission of pictures require about 4.2 MHz of bandwidth. A TV signal contains both voice and picture and is usually allocated 6 MHz of bandwidth for transmission.In the preceeding paragraph, we have considered only analog signals. Digital signals are in the form of rectangular waves as shown in Figure. However, for practical purposes, the contribution from higher harmonics can be neglected, thus limiting the bandwidth. As a result, received waves are a distorted version of the transmitted one. If the bandwidth is large enough to accommodate a few harmonics, the information is not lost and the rectangular signal is more or less recovered. This is so because the higher the harmonic, less is its contribution to the wave form.

Communication electronics can be classified as, (i) Analog communication and (ii) Digital communication In analog communication, analog signals are used. An analog signal is a continuously varying voltage or current. Traditionally, in telephone and radio systems, the messages consisted of information conveyed by voice.Shortcomings of analog communication is also explain in this video. A digital communication system offers many advantages to the user, that cannot be achieved with an analog system. Digital communications system may make use of analog links and concepts.The term data is commonly used in digital communication systems. Data is any form of information, that has been put into digital form, so that it can be handled by a digital system. Advantages (i) The transmission quality is high and almost independent of the distance between the terminals. (ii) The capacity of the transmission system can be increased. (iii) The newer types of transmission media such as light beams in optical fibers and wave guides operating in the microwave frequency extensively use digital communication. Disadvantages (i) A digital system requires larger bandwidth. (ii) It is very difficult to gradually change over from analog to digital transmission.

Tutorial materials found here: https://scipy2017.scipy.org/ehome/220975/493423/ In this tutorial I intend to start with a basic review of discrete-time signals and systems using a module I developed for my book Signals and Systems for Dummies. Once a basic foundation is provided, all using hands-on Python code examples in a Jupyter notebook, I will move to more advanced topics relative to statistical signal processing, digital communications and software defined radio. Digital communication transmitter and receiver simulations will be explored using Python code modules found in the newly posted scikit-dsp-comm as well as data acquisition code used in conjunction with a popular \$20 software-defined radio USB dongle (RTL-SDR). The capstone portion of the tutorial will have the students write code to recover FM stereo radio broadcasts from a raw complex signal file obtained from the output of a popular \$20 software defined radio module (the RTLSDR). Hardware will be provided for small groups to work together.
