Digital Signal Processing First, Global Edition
For introductory courses (freshman and sophomore courses) in Digital Signal Processing and Signals and Systems.Text may be used before the student has taken a course in circuits. DSP First and its accompanying digital assets are the result of more than 20 years of work that originated from, and was guided by, the premise that signal processing is the best starting point for the study of electrical and computer engineering.The "DSP First" approach introduces the use of mathematics as the language for thinking about engineering problems, lays the groundwork for subsequent courses, and gives students hands-on experiences with MATLAB. The 2nd Edition features three new chapters on the Fourier Series, Discrete-Time Fourier Transform, and the The Discrete Fourier Transform as well as updated labs, visual demos, an update to the existing chapters, and hundreds of new homework problems and solutions.

Global Digital Technology Convergence : Driving Diffusion via Network Effects
Since the 1970s, we have witnessed unprecedented diff usion of digital technologies in both speed and geographic coverage.These technologies are pervasive and disruptive, and lead to profound shifts and transformations in societies and economies.Many claim that emerging network externalities are the principal phenomenon driving the process of technology diff usion and determining its in-time dynamics. This book analyzes the unique role network eff ects play in the process of digital technology diff usion.Using the time span of 1980–2022 and data from over 180 countries, the authors examines the strength and determinants of emerging network externalities in the process of digital technology diffusion across the world.Moreover, using international case studies it traces the process of technology convergence and technology convergence club formation, intending to answer whether cross-country gaps are diminishing or rather growing, and if countries form unique ‘clubs’ within which a rapid convergence occurs. Global Digital Technology Convergence is written for scholars and researchers in the fi elds of technology and innovation management, information and communication technology, economic development and the economics of innovation.

What is a digital signal in signal processing?
A digital signal in signal processing is a discrete-time signal that is represented using a sequence of numbers. These numbers are typically binary and are used to represent the amplitude of the signal at specific time intervals. Digital signals are used in various applications such as telecommunications, audio processing, and image processing. They offer advantages such as easier storage, transmission, and manipulation compared to analog signals.
-
What is the difference between an analog signal and a digital signal?
An analog signal is a continuous wave that varies in amplitude and frequency, while a digital signal is a discrete signal that represents data as a sequence of discrete values. Analog signals are susceptible to noise and distortion, whereas digital signals are more resistant to interference and can be easily processed and transmitted without loss of quality. Analog signals are used in older technologies like vinyl records and analog phones, while digital signals are used in modern technologies like CDs, smartphones, and computers.

Can my television receive a digital signal?
To determine if your television can receive a digital signal, you need to check if it has a built-in digital tuner. Most modern TVs come equipped with digital tuners, but older models may require a separate digital converter box. You can also look for labels such as ATSC, DTV, or HDTV on your TV, which indicate its compatibility with digital signals. If your TV does not have a digital tuner, you may need to purchase a digital converter box to receive digital broadcasts.
-
Can a digital signal be an alternating current?
No, a digital signal cannot be an alternating current (AC). A digital signal is a discrete, binary representation of data, typically represented by two voltage levels (0 and 1). On the other hand, alternating current is a type of electrical current where the flow of electric charge periodically reverses direction. While digital signals can be transmitted over an AC electrical system, the digital signal itself is not an AC current.

How can I convert a digital audio signal to an analog signal on an MSI motherboard?
To convert a digital audio signal to an analog signal on an MSI motherboard, you can use the onboard audio connectors. Most MSI motherboards come with built-in audio chips that support analog audio output. You can connect your speakers or headphones to the audio output port on the motherboard to convert the digital audio signal to an analog signal. Additionally, you can also use a digital-to-analog converter (DAC) if you require higher quality audio output.

Why does the network socket have no signal?
The network socket may have no signal due to a variety of reasons. It could be due to a physical issue such as a loose connection or a damaged cable. It could also be caused by a problem with the network equipment or a disruption in the network infrastructure. Additionally, it could be due to a configuration issue or a problem with the network settings on the device. Troubleshooting the issue by checking the physical connections, network equipment, and device settings can help identify and resolve the cause of the no signal problem.

Why is my digital receiver not receiving a signal?
Your digital receiver may not be receiving a signal due to a few possible reasons. It could be a problem with the antenna or cable connection, so check to make sure they are properly connected and in good condition. It's also possible that there is an issue with the signal strength in your area, so try repositioning the antenna to see if that improves the reception. Additionally, there may be interference from other electronic devices or obstacles blocking the signal, so try moving the receiver to a different location. If none of these solutions work, it may be a problem with the receiver itself, in which case you may need to contact the manufacturer for further assistance.
