The principle of PWM wave speed regulation and the speed regulation method of tracking trolley

I. The concept of PWM and duty-free ratio ①PWM: Also known as pulse width modulation technology, is an analog control mode, the PWM waveform as shown below. ② duty cycle: refers to the proportion of the high level in a period. For example, a duty cycle of 50% means that the high level accounts for half of the period. Two, PWM fixed frequency speed regulation principle In the PWM speed regulation system, it is generally possible to change the dut

The future of optical solitons

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

Choose the best switching frequency for your DC/DC converter

: Capacitance and inductance values selected at 350kHz, 700kHz and 1600kHz frequencies Note that the higher the frequency, the smaller the number of laps required for the inductor, so the lower the DC impedance. the compensating parts for these error amplifiers are designed for the three switching frequencies in this article, but there is no discussion of how to calculate and select these component values. minimum on-time The minimum on-time controlled by a digital DC power converter is determin

Linux Clock Interrupt

From: In-depth analysis of Linux kernel source code (http://oss.org.cn/kernel-book/)The generation of clock interruptsThe physical cause of the Linux OS clock is the programmable timing/counter output pulse, which is fed into the CPU and can trigger an interrupt request signal, which we call the clock interrupt."Clock interruption" is a particularly important interruption, as the entire operating system is motivated by its activities. The system uses

"Arduino Official Tutorial First series" Sample program 6-3 Memsic2125 Accelerometer _arduino

Memsic2125 Acceleration Meter MEMSIC2125 is a two-axis accelerometer that can measure the acceleration of positive or negative 2g in two directions (g represents the gravitational acceleration). Its pin design is simple: Only two data output pins, one for the x axis and one for the Y axis. Its data output pins will output different pulse widths according to the size of the acceleration (do not know what the pulse

Replay attacks using the Arduino module to implement wireless signals

"shadow". The device used to replay the demo is a wireless control switch, which is more common in Europe, and it can remotely control the opening and closing of electrical appliances in a wireless manner.The device looks like this:In short, the signal is transmitted from the transmitting side to the receiving end in a non-zero encoded way, and then the receiving end decodes the signal and processes it. The non-zero code is a binary code: ' 1 ' Code positive voltage, ' 0 ' for negative voltage,

"Go" python Processing wave files

one of the applications of the resource Exchange file format (RIFF), which typically stores audio assets encoded with pulse encoding in chunks. It is also one of the most commonly used specifications in music enthusiasts. Because this audio format is not compressed, there is no distortion in sound quality, but the volume of the archive is larger in many audio formats. "We can see the above mentioned two keywords RIFF and
