disturbance energy is emitted to the surrounding space by the law of electromagnetic field. The common radiation coupling consists of three kinds: 1. The electromagnetic wave emitted by a antenna is accidentally accepted by B antenna, which is called antenna-to-antenna coupling; 2. The Space electromagnetic field is induced by the wire and is coupled, called field-to-line coupling; 3. Two high frequency signal induction between parallel conductors, c

generally composed of binary counters and decoders counting in the natural order. The shift sequence pulse generator consists of a shift register counter and a decoding circuit. The output of the ring counter is a sequence pulse, so the sequence pulse generator can be directly used without decoding circuit. II.

vase more beautiful! The following describes how to add the branches and leaves for the flowers and flowers. The production of leaves is very simple. Just cut a Green Paper like a leaf and fold out the veins ﹗ These are the materials to be prepared. You can buy wire for flower branches directly in the stationery store,If you already have a wire, you can also buy green adhesive paper i

Two 256kx16bit SRAM memory is used in diy_de2. The read and write operations of SRAM are relatively simple. The operations can be divided into hardware debugging and software debugging. Debugging environment: Quartus II 9.0 + niosii 9.0 1. hardware debugging That is to say, the simplest way to read and write the SRAM is to build the SRAM project and read the SRAM project respectively. First, write the SRAM. when the power is continuously on, read the SRAM. Finally, use SignalTap II to obse

problems may occur, or even serious circuit performance problems may occur.For example, Figure 1 shows the top layer of a dual-Panel designed for automatic cabling. The underlying layer 2 of this double panel shows the circuit schematic 3A and Figure 3b of these cabling layers. When designing this hybrid signal circuit board, the device is manually placed on the board to separate the numbers from the simulator.When using this wiring scheme, you need to pay attention to several aspects, but the

Author: Instructor Lu,Hua Qing vision embedded college lecturer. 4. Brief PCB design To compile the schematic diagram or the entire project, this step is to generate a network table and prepare for the work. Open it in project and project options. 4.1 DRC rules In terms of electrical rules, I searched for some annotations on the Internet for reference:Violations associated with buses various types of bus electrical errors (12 in total)Bus indices out of range bus branch Index out of rangeBus ran

(actually multiple strings are scattered in the array by hash, And the hash keyword is the array subscript) As you can imagine, the data structure is the same type of scattered containers in a freight yard. to link them together, you must install holes in the boxes with iron rings, then wire these wires can be mounted to the iron ring to concatenate them.The definition of struct list_head in the data structure is equivalent to an iron ring and can be

Line Speed Concept Many people misunderstand this line-speed concept. The so-called wire speed ability is the router/switch is like a wire. And this, is impossible. One of the concepts that should be considered is latency. Packet into the router or switch, there is a core delay operation, which is the routing, for routers, is the route lookup, for the switch is to query the mac/Port mapping table, this dela

Then, the Drop-down menu selects the Brush tool and does not tick "simulate pressure" to determine. 17, the font edge to get purple and white wire effect. Change the background color to black (#000000), select the "B Brush" layer, and then follow the same step to add a stroke path, into black and purple m

Wave automatic soldering technology has been used in the electronics industry for many years, but the late failure of solder joints is still a headache, which greatly affects the quality and reputation of electronic products.This paper intends to make a preliminary study and discussion on the basis of practical experience.The so-called "late failure of solder joints", refers to the surface appears to be the quality of the solder, there is no "lap welding", "Half welding", "pull the point", "copp

Picture of Tp-link Electric cat appearance 　What is a power cat? Power Cat, also known as the Power Network Bridge, is a network signal modulation to the wire, the use of existing wire to solve network wiring problems of the equipment. The utility cat is similar to the router in use, and the current mainstream power cat supports WiFi wireless function, can solve the smartphone, the tablet computer and so

Network cables can provide good anti-interference performance, ensure normal transmission, and maintain good confidentiality. The shielding structure of Shielded Cables has inherent advantages in reducing mutual interference between cables, it not only shields external electromagnetic signals, but also blocks the electromagnetic leakage of cables. It does not emit interference signals, affecting other cables and preventing information from being eavesdropped. In the shielded network cable, ther

The purpose of twisted pair wire shielding is to cut off the path of Space electromagnetic radiation to the core line of the twisted pair wire, or to reduce the intensity of Space electromagnetic radiation. The traditional shielded twisted pair wires (such as F/UTP and SF/UTP) are used to add multiple shielding layers (such as aluminum foil shielding layer and copper mesh braided shielding layer) to the out

, but with a glance at the mess in the past, and the colorful and colorful, green, then even if your electrical performance is good, in the eyes of others, it is still a piece of garbage. This will cause great inconvenience to testing and maintenance. The wiring should be uniform, and there is no way to do it. These must be achieved when the electrical appliance performance is guaranteed and other individual requirements are met. Cabling is performed based on the following principles: ①. In gene

controllable, the characteristic impedance is also controllable. The Characteristic Impedance z0 of the microline is:Medium: [er is the relative dielectric constant of Printed Board Media6 is the thickness of the dielectric layerW is the line widthT indicates the wire thickness.The transmission delay time of a line with a unit length depends only on the dielectric constant and is independent of the width or interval of the line.(3) cables in printed

side arc) from the side, in order to ensure the accuracy of the side arc, you can add blocks of different heights to one end of each rib deck (called a pedestal pole ). The height of each rib plate pedestal can be measured from the line at the beginning and end of the lateral view in the model drawing. When fixing a rib plate, pay attention to the coincidence between the midline of the rib plate and the center line of the pedestal plate. To facilitate the split, the rib can be temporarily fixed

triangle. 32. There are 1001 wires at the bottom of a building, which extend to the roof of the building. You need to determine the relationship between the underlying 1001 wire headers and the 1001 wire headers on the roof. You have a battery, a light bulb, and many very short wires. How can we determine the ing between the wire and cable headers only once?
