pillars" world, communication is the third pole in addition to hardware and software. In any case, communication is what really makes everything interesting. With the communication between computers to communicate with each other, and this communication is for us to provide convenience. The web was born in the middle of the 1990, and it turned the internet of few people into a daily necessity for every one of us.The network transforms the information into physical representations so that it can
This week in the teacher's recommendation I read the "World is Digital" this book, did not think about this aspect of the books, when reading this book, I have a lot of unexpected harvest. Get a lot of valuable information, some small problems in life have been answered, the content of their own professional learning has a deeper understanding.In this age of our
The Book of the World is digitalIn the first moment, in my impression, software engineering is mainly about the use of computers. The research field of computer science is divided into: computer sciences, Computer engineering, software engineering, information system and it. In my opinion, nowadays, computers are for everyone to master."The world is digital" beca

Article Description: This thinking about e-book design stems from a recent experience and discussion of usage. Accustomed to the Kindle Physics key flip-screen reading, the Kindle touch of the screen operation is very unaccustomed (contact evoked), or even startled! Do not like E-books, in addition to not be free to write painting, the bigger problem is that e-books can not give the same experience as tradi

In the previous section, we talked about the Library management system login, I believe that we have a jade template and angular JS also have a understanding, today we look at a book information input. Here we are going to use the NoSQL database, which is used by MongoDB in this blog post. Ok. Mongo DB Installation I don't have to say much, then the node.

Encryption and decryption use the same key algorithm, called symmetric encryption algorithm. encryption and decryption use different keys, called asymmetric encryption algorithms. The public key system is an asymmetric encryption algorithm. For symmetric encryption, symmetric keys must be protected. For public key algorithms, private keys must be protected.Public key encryption algorithms and derived digital

still ignorant of the years.How many people have worked in the software industry for many years, and how many people involved in a variety of cool framework development, system development? How many architects can lead parallel development of systems with more than 50 people? Or, we ask ourselves, how many lines of code have been wasted in order to cater to design patterns, how much complexity has been add
Article Description: currently in the user-led design to take digital guide design of the main concentration of four types of Web sites or Products: (1) shopping sites, such as group purchase stations, they use numbers to create a scarcity of impressions and incentives to follow suit; (2) system optimization software,
The book comes from a world-class designer. Complex design principles in the book condensed into intimacy, alignment, repetition and contrast 4 basic principles. The author, with its concise and lively style, presents the 4 basic principles and the principles behind which the excellent design must follow. This
Article Description: motivate users with numbers? Scenarios and user-led surprises.
Sociabeta before the article "4 kinds of clever use of" digital to motivate the user behavior of the method, describes some use of digital to motivate user behavior of the case design. Recently happened in a project, involving digit
Order N are determined, the N-point FFT of H (n) can be determined in the frequency domain, expressed by H1 (k. Therefore, there are:
It can be seen that when L is an integer multiple of N, H (k) can be obtained by interpolation H1 (k) to O and proportional amplification ).(2) assuming that the filter has linear phase characteristics, the samples of H1 (k) available amplitude function and phase function are represented:
The above analysis shows that H (k) can be calculated as long as the Order
voltage changes are discrete rather than continuous. In addition, the components of the loop are all implemented using digital circuits. Therefore, this phase-locked loop is called the full digital phase-locked loop (PLL ). The Digital Phase-Locked Loop consists of the Digital Phase Detector, reversible counter, frequ
realized that it was just a matter of novelty. However, this book, the company, and the author have an inexplicable yearning.
After graduation, I borrowed this book from my organization. I don't know why, but I always think that the book has its own "Yan ruyu ". It wasn't until you started to get into touch with the processor
frequency, the impedance of the RLC model is the smallest and the impedance is zero.
For the RLC series model, the approximation is as follows:
The larger the resistance, the smaller the Q value. The larger the inductance, the larger the Q value. The larger the capacitor, the smaller the Q value.
