During the differential transmission of twisted pair wires, for external interference signals, the two twisted pair wires are equivalent to the Same conductor, and the interference signals have the same amplitude and polarity on the two wires. At the input end of the differential amplifier, if the CMR value of the two-wire common mode input is large enough to receive the difference amplifier, it can be well

To introduce the push-pull circuit, first introduce some basic knowledge about the power amplifier. From the point of view of energy control, there is no essential difference between the power amplifier circuit and the voltage amplification circuit, but the latter requires that the load receive a voltage signal without losing its original strength, the requirement of the former is to get a certain amount of

your router does not cover up a remote area, you can DIY it and add wireless signals to cover up the area. The most popular DIY tips are the use of tin paper, aluminum cans or stainless steel filters to enhance the signal. Although the role will not be exaggerated, at least you don't have to spend too much effort to add a signal to cover up the area. Modify it to enhance the router signal.Another good way to add the signal to cover up the area is the device DD-WRT firmware, so that not only can

grounding system to talk about its design. 1 public broadcasting and paging system The hotel broadcasting and calling system is divided into two categories. One is a public system for public areas (such as the lobby Exhibition Hall and the front-end service area of the hotel). Background Music is broadcast at ordinary times, in case of fire or emergency, it can be switched to emergency broadcast, the second is the Broadcast System for office conference areas and garage areas (professional broad

It is equivalent to a wave file and does not require decoding. You can directly input a Power Amplifier for DA conversion. Because of the large bit rate and volume, in the DVD era, audio tracks are usually used in two-channel music discs. When the Blu-ray disc is used, the transmission rate and ca

too far. It is best to deploy these three video lines. For example, if the computer is in the study room and you want to use the living room to play videos on the computer and other program content, deploying vga will make this idea a reality. The video lines are relatively rough and it is difficult to expose them to the outside. At the same time, because of the large amount of signal loaded by the color difference line and the DVI line, there is a high requirement on the quality of the wire. P

can be done automatically when the NI pxie-5644r self-calibration process is run.Receiver Signal PathThe NI pxie-5644r Receiver is designed with the top-level architecture shown in 6. This block diagram shows the calibration synthesizer, an optional high power attenuator, an optional low-power signal amplifier, an out-of-band filter, additional gain and attenuation signal conditioning, and a mixer (three) for demodulation based on frequency selection

circuit can be used to lift a near-ground voltage to a predetermined range, the only thing to note is that the output range of the TL431 is not full-width.The TL431 itself has a fairly high gain (I have a rough test in the simulation, about 46db), so it can be used as an amplifier.Figure (5) shows a DC voltage amplifier composed of TL431, the amplification of this circuit is determined by R1 and Rin, equivalent to the OP amp negative feedback circuit

". At this time the drawings "A1.schdoc" internal C1, C2 can and drawings "A2.schdoc" in C1, C2 connected, the same blueprint "B1.schdoc" and "B2.schdoc" can also be connected to the network, but these two groups will not be network connectivity (paper A1.schdoc C1 is not connected to B1.schdoc C1). This is the function of the cross-drawing interface, which can increase the sheet range of the chart symbol.Three, design example 3.1 design ideasNow to design a 2.0 bass

Overview of twisted pair wires and coaxial cables During the differential transmission of twisted pair wires, for external interference signals, the two twisted pair wires are equivalent to the Same conductor, and the interference signals have the same amplitude and polarity on the two wires. At the input end of the differential amplifier, if the CMR value of the two-wire common mode input is large enough to receive the difference

common-mode signal m and the differential-mode signal n.where m= (a+b)/2;n= (A-B)/2.The difference amplifier makes two signals as the output signal. The output signal is a-B, compared with the common-mode signal and the differential mode signal in the original two signals, it can be found that:The common-mode signal m= (A+B)/2 is missing, while the differential mode signal n= (A-B)/2 gets twice times the magnification.This is how the differential mod

leakage. And the leakage is divided into three kinds of situation, each has its own methods: 1, small current leakage, regardless of size, the above electrical power supply does not protect whichever. Leakage current in more than 100MA, usually have obvious fever, we can go to touch, find the heating element. If the heat is not too obvious, can be appropriate to improve the voltage, but for the sake of safety voltage should be controlled within 8V, the current to no more than 200MA appropriat

Asp.net|web compared to previous ASP versions, ASP. NET has been greatly improved. Among these improvements, the main point is the newly introduced server-side controls. Now we're going to work together on the HTMLControl and WebControl in asp.net, two types of server-side controls. Recall: An example of not using a server-side control To illustrate the benefits of the server-side controls, we now use the traditional ASP to make a page. The function of this page is to display some commen

The series

After reasonable management, two kinds of distortion factors (dispersion and self phase modulation) in optical fiber can cancel each other, so that the optical soliton can play its role. The color closing causes the pulse signal containing a group of wavelengths to diverge gradually with the increase of the transmission distance. Self-phase modulation (SPM) spreads the spectrum of light pulses horizontally. These two distortion factors have a certain relationship, they can balance each other, so
