This article describes in detail the origins of the ultra-wideband wireless access technology, developed from the wireless UWB technology, that is, the pulse radio technology. It is used in a broader field and is integrated with our daily lives. It not only facilitates entertainment and work. Ultra-Wideband Wireless Access Technology According to the problems of serious narrowband interference and average power ratio of MB-OFDM signal in ultra-wideba

I've seen the Handbook of motion control chips before, including Nova's MCX314 and PCL6045, and know the concept of interpolation.But what exactly is interpolation, in fact, has always been a little puzzled, and then silly to ask some experts, their argument is:Interpolation can be multi-axis output at the same time, fast. And then I don't know what to ask.Based on my previous experience in stepping motor, as well as my experience in testing stepper motor drivers, I typically use a single-chip m

. The most common Ethernet standard in a data center is 1000Base-T or 1000Base-TX, some data centers have started to adopt 10G Base-T. Therefore, this article will mainly study the relationship between these three standards and off-line crosstalk. This article will begin with the three standard modulation methods, analyze their ultimate signal-to-noise ratio, and then compare the signal-to-noise ratio that can be achieved by the transmission media, finally, let's take a look at the influence of

Principle and method of laser rangingThe laser ranging coarse divided into two kinds, the first principle is roughly half the product of the speed of light and round-trip time, is the distance between the rangefinder and the measured object, taking the laser rangefinder as an example; the second is a method based on the principle of laser displacement sensor.There are roughly three methods of laser measurement, pulse method (laser Echo method), phase

, each clock cycle will have a hop, which is a bit synchronization signal. Differential Manchester encoding is an improvement in Manchester encoding. It has a hop in the middle of each clock bit. The transmitted value is "1" or "0", which is determined by whether there is a hop change at the beginning of each clock bit. Differential Manchester Coding has fewer changes than Manchester Coding, so it is more suitable for transmitting high-speed information and is widely used in Broadband high-speed

The last time we used AutoResetEvent to implement a production/consumer queue. This time we will use the Wait and Pulse methods to implement a more powerful version, which allows multiple consumers, each running in their own thread. We use arrays to track threads. Thread [] _ workers; Through the tracking thread, we can end our queue tasks after all threads are finished. Every consumer thread executes a method called Consume. In a for loop, we can cre

so that they can be used for javafx. It is also responsible for thread-related rules and event processing. Glass wing Toolkit In the middle of Figure 1, the glass drawing wing toolkit provides local operation services, such as management windows, timers, and appearances. It provides services to connect to the javafx platform and local operating systems. The glass Toolkit can also process event queues. Unlike AWT, it not only manages its own event queue, but also local operating system events.

From: http://www.eepw.com.cn/article/73889.htm Stepper motor is an electromechanical component that converts an electrical pulse signal into an angle displacement or linear displacement. The input value of the stepper motor is a pulse sequence, and the output value is the corresponding incremental displacement or step motion. Under normal motion, it has a fixed number of steps each week. When performing Con

of exercise, the body may lose some weight due to the increased metabolism, high body fat and water consumption. After a period of time, due to changes in muscle mass and volume, the weight will remain at a relatively stable level. With the increase of age, the weight should gradually increase. Under normal circumstances, after each exercise, the weight is reduced more or less, and after rest, it can be restored to the original level. You can measure and compare the weights before and after exe

manager gave Zhang San a stack of A4 paper: "There are thousands of kinds of signals, all in the formula, the input signal duration is also determined." What do you test the output waveform of our products separately? "This Zhang San Meng, he was thinking "God, help me, how do I draw these waveform diagram?"So God appeared: "Zhang San, you just have to do a test, you can use the mathematical method to draw all the input waveform corresponding output waveform."God went on to say: "Give the produ
