It's not that the two of them have a long angle on their heads. It's very strange. You need to understand why you need to separate them. First, let me tell a story.The business building of our company is located on the third floor, the second floor is simulated, and the third floor is digital. There is only one elev

(1) Message Summary: message Digest, also known as a Digital digest (digitally Digest). It is the only fixed-length value that corresponds to a message or text that is generated by a one-way hash encryption function that acts on the message. If the message changes on the way, the recipient can tell whether the message has been changed by comparing the newly generated digest of the received message with the original digest. The message digest theref

1. Introduction to Digital certificatesThe digital certificate has the necessary information of general encryption and decryption, including the signature algorithm, which can be used for network data encryption and decryption interaction to identify network user (computer) identity. Digital certificate provides a simple way to publish public key, and its

I. Overview of digital signal processing 1. Digital Signal (1) signal: a signal is a carrier for carrying information. Without information, the signal will be meaningless. (2) digital signals: Signals processed by computers 1) Representation: X [N], which is a vertical line with a circle on the top. 2) digital signals

The way to make digital in the future--Siemens ' digital experienceSince ancient times, with "abundance" reputation of Chengdu is a good place to enjoy the ease of life. Ease of life may be a good friend invited to play a game of mahjong, or small groups in the narrow alley of the shadow staggered between a cup of tea. However, in addition to ease, Chengdu has also been changing, the national "West developm

Digital Certificate and Its Application in Security Testing0x00 background To perform security tests on the Web layer, it is inevitable that a man-in-the-middle proxy will be used to capture packets for analysis. Common tools include BurpSuit, Fiddker, and Charles. The usage of these tools has been described on the Internet. I will not go into details here. However, when testing websites with high security, you may encounter SSL communication problems

while millions of people starved to death. now we have an insatiable hunger for knowledge. yet a great deal of data remains unused. Part of the problem has to do with the way information is displayed. someone once said that if we tried to describe the human brain computer terms, it looks as if we have a low bit rate, but very high resolution. for example, researchers have long known that we have trouble remembering more than seven pieces of data in our short-term memory. that's a low bit rate.

∑– analog-to-digital converter (ADC)1. OverviewIn recent years, with the improvement of VLSI manufacturing level, sigma-Delta analog-to-digital converter is widely used for its high resolution , Good linearity and low cost . Sigma-Delta Analog-to-digital converters the proposal was already made in the 1960s, however, until recently, this process was not feasible

According to the different signal modes, communication can be divided into analog communication and digital communications. What is analog communication? For example, in telephone communication, the electrical signals that are transmitted on the user's line vary with the user's voice size. This changed electrical signal, whether in time or amplitude, is continuous, which is called analog signal. The mode of communication that transmits analog signals

Introduction With the increasing market demand for symmetric digital cables (hereinafter referred to as digital cables) for integrated cabling, many optical cable manufacturers have begun to develop and produce such cables for this manufacturer to meet market demands. At the same time, the manufacturer found that although the digital cable and the early municipa

If we regard "digital oilfield" as a complete and advanced computer software and hardware, we can't help but wonder how long can we maintain this advanced nature? For example, if we buy a personal PC in our family, there are many PC categories, nearly 20

Summary of simple digital clock designIn the information age, the concept of time is deeply rooted, so mastering the design of digital clock has certain epoch significance, and using Multisim to design digital clock for discrete components can greatly improve the quality of personal digital circuits.The design idea is

In the design of electronic system, in order to avoid detours and save time, we should fully consider and meet the requirements of anti-jammingAfter the design is completed, the remedial measures for anti-jamming are carried out. There are three basic factors that form interference:(1) The interference source, which is the component, device or signal that produces the disturbance, is described in mathematical language as follows: DU/DT, di/dt large landSide is the source of interference.
