benefits of encapsulation: the member variables of a class can be read-only or write-only; A class can have a holistic control over what is stored in its member variables; The user of the class does not need to know how the class stores the data and implements the reuse of the code.Static member: Keyword static allows a member variable or method not to be associated with a specific instance of a class. A member variable or method declared through the keyword static can be considered global, and

In this series, I learned some very useful functions from C # together with everyone. For some people, they may be inconspicuous, so they are often ignored. They won't yell: "Use me! I will save you a lot of time and make your code more concise !" -But these words will emerge from the minds of programmers who are familiar with them.
Okay! Let's take a look at ToLookup:

been adopted in the industry, making it a reality to transmit 10 Gigabit copper cables at a distance of 100 meters. Specifically, the industry has adopted a lot of new designs, including cables, module structures, and connections, including the use of new materials, new manufacturing technology, change the relative position of the four pairs of cables, change the module printing circuit design, etc. to improve ANEXT performance, to meet the requirements of 10g transmission. Of course, because d
. If the filter parameters are inaccurate, the system will eventually cause frequency conflicts. In turn, the design group will have to deal with crosstalk, disconnection, data loss, and network connection interruption.
The incomplete or inaccurate definitions of filters are partly due to the current popularity of digital electronics in the electronic market. According to some statistics, 80% ~ 90% of new electronic design engineers are software and d
XieMeng-xian. (Emy of electronics, Chengdu) (1) Why does the thickness of p-n junction barrier become thinner with the increase of doping concentration? -- In the heat balance, a certain amount of space charge can generate a definite Built-in Electric Field to offset the diffusion. However, in the close proximity of the consumption layer, space Charge is mainly the charge provided by the ionic impurity center, so when the doping concentration is certa
ARM announces the launch of the latest 32-bit cortex-m processor CORTEX-M7, which delivers up to twice times more computing and digital signal processing than the currently highest-performing ARM architecture microcontroller (MCU) ( DSP) performance. The ARM cortex-m7 processor is designed for high-end embedded applications for next-generation automotive electronics, networking equipment, and smart home and industrial applications. The first vendors

pixel data at the time of transmission, and each clock cycle transmits 10bit of data. The pixel clock cycle transfer ratio is approximately 25MHz to 165MHz. In general, the standard NTSC 480i interlaced signal has a pixel clock transfer ratio of approximately 13.5MHz. If the ratio of the transmission signal is less than 25MHZ,HDMI will use automatic cycle technology to fill the code rate, the signal rate to increase to 25MHz level. While the HDMI interface can transmit up to 165M of data per se
