This book aims to cover a new emerging need in designing digital phase shifter for modern communication systems. With the advancement of new generation mobile communication systems, directed beams of antenna arrays save a substantial amount of power as well as improve the communication quality. In this regard, beam-forming circuits, such as digital phase shifters (DPS) constitute essential parts of the antenna array systems. Therefore, this book is devoted to the design of digital phase shifters for various communications systems. Nowadays, phase array systems demand compact phase shifters suitable for chip implementation with wide phase-range and broad frequency band. For each phase shifter topology introduced in this book, the reader is furnished with explicit design equations to construct the circuit under consideration. Furthermore, design equations are programmed using MATLAB to assess the electrical performance of the phase shifters with ideal and lossy components. MATLAB design programs are given at the and of each chapter as appendices and provided as soft copy on the web page of the book.

This book introduces the basic analysis methods in signal processing, principles of various sensors and the concept of measurement system. To make students better understand and apply the theories, the book includes many MATLAB examples, such as the generation of standard signals and the spectrum analysis of audio signals in the signal processing part and Arduino examples as well, such as temperature measuring and ultrasonic ranging to show the applications of sensors. Readers can not only learn the fundamental theories but also get many opportunities to apply the theories to perform measurement tasks. Ultrasonic Ranging Device Based on Arduino: The principle of ultrasonic ranging has already been explained. With an ultrasonic ranging module (HC-SR04), we can build our own ultrasonic ranging device. The reference code below needs a computer to display the measured distance. We recommend you try to add an LCD screen to display the distance and use a battery to power your board, so you can build a portable device.

The ESP 32 is a low cost system on chip series created by express systems. It's an improvement on the popular SB eight two six six that is widely used in Internet of Things products. ESP 32, has both Wi-Fi and Bluetooth capabilities, which make it an all rounded chip for the development of Internet of Things project and embedded systems engineer. Now, in this course, you will learn how to get started with that iOS P32 and learn how to use it to scan Wi-Fi hotspots, control LEDs, buttons, sensors or get sensors reading on our page along with other examples. This course will equip you with the basic knowledge that you will need when working on your ISP. 32 projects in the future. It's basically an Internet of Things development framework that they provide for their boards. There is also Micro Python, jаvascript or Lua, the ones that we are going to use, and this course is Arduino I.D. It requires some adjustments to install the ISP library, but everything will be explained in details in a separate section.

The computing paradigm offered by analog computing is nearly forgotten, although it offers a path to both high-speed and low-power computing, which are in even more demand now than they were back in the heyday of electronic analog computers. This book provides a comprehensive introduction to analog computing. This second expanded edition contains the recent advancements of the last eight years. A book on analog computing and analog computers? You might ask: Isn’t that 60 years late? No, it isn’t – although the beautiful analog computers of the past are long since history and only few have been preserved in museum collections, the idea of analog computing is still a marvel of elegance and the following chapters will show that it has a bright and fruitful future. The intention of this book is twofold: It gives a comprehensive description of the history and technology of classic analog computing but also shows the particular strengths of the analog computation paradigm, which, combined with current state of the art digital circuitry, will find applications in areas such as low power computing, high performance computing and maybe most importantly in Artificial Intelligence (AI) and many other fields.

This book provides a detailed introduction to near-sensor and in-sensor computing paradigms, their working mechanisms, development trends and future directions. The authors also provide a comprehensive review of current progress in this area, analyze existing challenges in the field, and offer possible solutions. Readers will benefit from the discussion of computing approaches that intervene in the vicinity of or inside sensory networks to help process data more efficiently, decreasing power consumption and reducing the transfer of redundant data between sensing and processing units. Neuromorphic computing dreams of human-level artificial general intelligence by emulating the brain, which contrasts the pervasive von Neumann computing architecture. Up to now, artificial synapses have been long and widely adapted to function mostly as signal transmission with a memory effect in neuromorphic computing; significant efforts have been made to mimic mostly the memory function (e.g., memristors). However, emulating synaptic computation, which is vital for information processing, working memory, and decision-making by using short-term plasticity (STP), remains technically challenging to be demonstrated without using numerous CMOS devices. In the human brain, a quadrillion synapses are present in a massively parallel architecture, which highlights the issue of integration of CMOS devices for an efficient neuromorphic chip.

The Internet of Things (IoT) is becoming a major application area for embedded systems. As a result, more and more people are becoming interested in learning about embedded design and programming. Technical colleges and universities are moving away from legacy 8 and 16-bit microcontrollers and are introducing 32-bit embedded microcontrollers to their curriculums. Many IoT applications demand precision, high processing power, and low power consumption. Produced by IBM, Node-RED is an open-source visual editor for wiring the Internet of Things. Node-RED comes with a large number of nodes to handle a multitude of tasks. The required nodes are selected and joined together to perform a particular task. Node-RED is based on flow type programming where nodes are configured and joined together to form an application program. There are nodes for performing complex tasks, including web access, Twitter, E-mail, HTTP, Bluetooth, MQTT, controlling GPIO ports, etc.
