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

, 3, change the armature circuit resistance. The use of single-chip microcomputer to control the speed of the DC motor, the general use of the method of regulating the armature voltage, through a single-chip microcomputer control pwm1,pwm2, to produce a variable pulse, so that the voltage on the motor is also a variable width pulse voltage. According to the formula U=avcc Wherein: U is the armature voltage

waveform generated by the pulse after the complex value symbol mapped by multiple digital bits is the basic time particle that forms the sub-frame/frame of the system. In engineering, we also use an eye chart to observe the waveform changes in a single symbol cycle in the baseband waveform and determine whether there is inter-code crosstalk. Iii. IQ mediation-Basics of digital/simulated mediation IQ mediation is a very important engineering method. C

First, the Irig serial timecode format Introduction:Irig-b is a per-second frame of the serial timecode, the total width of each code element is 10ms, a time frame period consists of 100 code elements for pulse width coding. Each code element has 3 code types: binary 0, 1, and positional identifiers. Divided into 3 field codes: The 1th field is year (year, day, hour, minute, second), the 2nd is the Control function number field, and the 3rd is the tim

(Strobe, Initialize Printer, Select Printer, and Auto Feed line) and five status lines (Busy, Acknowledge, Select, Paper Empty, Fault), need three different registers for data read and write operations. The SPP mode is the most basic working mode. asynchronous and byte one-way transmission has a data rate between 50KB/s and 150KB/s. The AB-cable can be used for 6 meters, while the new CC-cable can be used for up to 10 meters. Time series of the basic SPP Mode When the printer is ready to recei

The multimedia is suspended. Let's talk about a few irrelevant theme words. Although it can behave like nothing, it is quite lost. I have never believed that scores can be used to measure a person's level or something, but I still have a bottom line on my requirements. The bottom line is that I stick to my own style of capital. Over the bottom line, all justified reasons will turn into the arrogant requirements of the 80 s. Why have I fallen to the point where I am not involved? How can I spend

voltage changes are discrete rather than continuous. In addition, the components of the loop are all implemented using digital circuits. Therefore, this phase-locked loop is called the full digital phase-locked loop (PLL ). The Digital Phase-Locked Loop consists of the Digital Phase Detector, reversible counter, frequency switching circuit, and n-frequency divider. The reversible counter and the N-divider clock are provided by the external crystal oscillator. VCO is not used to greatly reduce t

conventional optical fiber communication forward development We know that the loss and dispersion of optical fiber are the two main factors restricting the transmission distance and capacity of linear optical fiber communication systems, especially in high speed optical fiber communication systems above gbit/s, the dispersion will play a major role, that is, because the pulse broadening will reduce the system capacity and the distance of transmissio

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
