Title DescriptionDescriptionThere is a circuit with n components on it. The probability that I was broken is known as pi (i=1,2,3,..., n,0The connection of the components is simple, the circuit is represented as follows:1, a component is the smallest circuit, with a means component 1,b represents the component 2, and so on.2, K

First, let's look at the concept of the next grouping. The so-called grouping is to divide a packet into smaller packets. For example, for a 10GB packet, it is not always a one-time delivery of the past bar, but it is divided into a number of small packets sent past. Structure diagram for each block of data:File headers are typically descriptive data, such as source and destination addresses, data types, and so on. The data part is what is really going to be communicated to the objectCircu
The so-called power transfer is the input voltage through the pressure circuit to achieve the lift/buck function for the use of other modules, intelligent car production, the input battery voltage of 7.2V, the other modules required voltage as follows: Minimum system board/oled/Eagle Eye camera 3.3V, op amp power supply ±5 V, servo power supply 6V, Drive circuit 12V, ccd/encoder 5V. The following is about t
Application of RJ45 short circuit ring on gigabit Nic1. Topic OriginFor those who often work on multiple operating systems, using Windows as the host system with Vmware Workstation is already a standard Workstation. I personally traveled back and forth between Windows and Linux and used the notebook configuration as Windows 7 as the host, VMWare Workstation 9 to install the Virtual Machine CentOS and OpenBSD. Virtual Machine network connection is set
First, let's get to know several "regions": "hot" refers to areas directly or indirectly connected to the AC power grid; "cold ground" refers to a region that is not connected with the power grid. A signal "Ground", also known as a reference "Ground", is a reference point with zero potential, it is the public end that forms the circuit signal circuit. The "ground" of protection is in Class I electrical equi
In a microservices architecture, the service is split into services according to the business, and the service and service can call each other (RPC), which can be invoked with Resttemplate+ribbon and feign in spring cloud. To ensure their high availability, a single service is typically deployed in a cluster. Due to network reasons or their own reasons, the service does not guarantee that 100% is available, if a single service problem, call the service will be a thread blocking, if there is a la

In analog electronic technology, we need to master the basic structure of the basic components and the characterization of the main parameters from the contact of simple diodes to transistors (BJT) to integrated circuits. I will not elaborate on the internal components of diodes and transistors (BJT), which can be described in more detail by reference to the relevant information.
In the transistor, a very important value is the static work point Q, the static operating point Q for the transisto
Pay attention to the following basic items for the current loop:
1. If you use strip, try to bold it.
If the Grounding Connection on the PCB is to be considered, the design should be as rough as possible. This is a good rule of thumb, but you must know that the minimum width of the ground wire is the valid width from this point to the end. Here the "end" refers to the farthest point from the power connection end.
2. Ground loop should be avoided
3. If the ground plane cannot be used, a s
The differences between circuit switching and group switching and their advantages and disadvantages are briefly described.Answer: 1) circuit switching: prior to communication, circuit switching requires the establishment of a physical path exclusively exclusive to both parties (composed of the switching devices and links of both parties). Therefore, it has the f
In certain dc/dc-converter applications, on-chip, cycle-by-cycle current limit could be insufficient protection to prevent a Failure during a short circuit. A nonsynchronous boost converter provides a direct path from the input to the short circuit through the inductor and the C Atch diode. Regardless of Current-limit Protection in the IC, when a short circuit ex

The reason for the use of chip magnetic beads and chip Inductance: whether the use of chip magnetic beads or chip inductance is still applied. Chip Inductor must be used in the resonant circuit. The use of chip magnetic beads is the best choice to eliminate unwanted EMI noise.
1.The unit of the magnetic beads is Ohm, not Hunter.Pay special attention to this. Because the un
The line output circuit is an important circuit in the display circuit. In the event of a failure, the monitor will not function properly. In actual use, the output circuit of the monitor often appears short-circuit fault, Open-circuit
a simple and effective charging equalization circuit for Li-Ion battery
This equalization circuit is made up of three identical parallel-regulated circuits, one for each battery.
Schematic diagram of the circuit is as follows:
Each regulated power supply is regulated to 4.2V. The principle of equalization is that when the battery voltage is less than
What is a soft printed circuit board? Starting in 1960, V dahlgreen attached a metal foil line to a thermoplastic film. Then, the flat cable is replaced to form a printed circuit line pattern on the soft insulation board. In the end of the 1960 s, after the PI (Polymide) substrate film was imported and used, so far, the software Board has continued to develop rap
Electric Mosquito pattern is a new type of small household appliance for mosquito control. The working principle of this product is to use the electronic line to boost the generation of power. At present, such products on the market use dry batteries for power supply, and also use batteries for power supply. The principle is that the output power is very small after the pressure is increased to kill mosquitoes through discharge, which does not affect people or pets.It powers on the metal mesh, a
