characteristics of high voltage regulation precision, no use of power transformers, etc, it is an ideal regulated power supply. Because of this, switching type regulated power supply has been widely used in a variety of electronic equipment, this paper describes the working principle of various types of switching power supply.I. basic working principle of On/Off regulated power supplySwitch-type regulated power supply control methods are divided into two types: Width Adjustment and frequency mo

, the output fluctuation is small, the linearity is good, the interference to the neighboring circuit is small, but the power device works in the linear zone because the heat will consume most of the electric power, the efficiency and heat dissipation is serious, so this method is only used for the drive of the Micro Power DC motor. The majority of DC motors adopt switch Drive mode . The switch driving mode is to enable the semiconductor device to operate in the switching state, through the

For a frame of 11-bit data 0.000104166666666667x11 = 0.00114583333333334 The data can be transmitted within one second. 1/0.00114583333333334 = 872.727272727268 872.727272727268 frames of data. Of course, this is only calculated in numbers, but there are actually many invisible latency factors. Experiment 10: Serial Port receiving module In terms of seria

. When other threads access an object, the calling thread will wait. The pulse signal is used to notify the waiting thread of changes to the object state. Pulse (), PulseAll () sends signals to one or more waiting threads. This signal indicates that the status of the waiting thread lock object has changed, and the lock owner is ready to release the lock. Wait for the thread to be placed in the ready queue o

take a specific implementation-8051 built-in UART for analysis. The 8051 built-in UART can work in four modes through software programming: Mode 0, Mode 1, Mode 2, and mode 3. Here, we will briefly analyze the asynchronous communication process using the commonly used 1-8 bit UART with variable baud rate. The frame size of Mode 1 is 10 bits: one start bit (0) + eight data bits (minimum valid bits first) + one stop bit (1), at the receiver, the stop bit is sent to the serial port's control regis

the server side works. pulse pulse is more like a short message, is also sent on the connection. The most important feature of a pulse is that it is asynchronous. The sender is not required to wait for the receiver to answer, and can proceed directly. However, this kind of asynchrony also brings a limitation to pulses.

time front of the time point is aligned with the front of the reflected wave, the number displayed on the digital monitor is the fault point distance.3. How to determine the nature of fault points1) when the line is normal, there is no reflection.2) when the line is disconnected or the contact is poor, the reflection pulse is the same as the emission pulse.3) the insulation is reduced when the line is shor

Therefore, the combination of good plastic sealing materials and lead frame can be used to improve the process and methods to prevent internal leads from being broken during encapsulation, so as to improve product sealing and device stability. Definition of Photoelectric Coupler Parameters The technical parameters of optical coupling can be divided into several parts: input, output, transmission, and isolation. 3.1 input features The input characteri

converter, it determines that it must occupy a certain amount of space and consume a certain amount of power in the system. Therefore, in system solutions that require convenient portability, the static D/A converter has to be replaced with [1].So people choose the so-called "Digital basis" D/A converter. There are two methods for digital D/A conversion: PWM (P Ulse Width Modulation) Pulse Width Modulation and PDM (

Basic commands The following basic AT commands allow you to call, select a dialing method (audio or pulse), control the speaker volume, and perform other basic modem operations. Important: you must use the AT command in the "command" mode of the communication softwa

Distributed Optical Fiber Temperature Measuring System Based on backward scattering principles can be divided into three types: Based on Fourier scattering, based on Raman scattering, and based on Bayesian scattering. At present, the development is relatively mature, and some products are applied to engineering Distributed Optical Fiber Temperature Measurement System Based on Raman scattering. Its sensing princi

N LCD start control bit (ENB) When ENB is set to 0, all LCD pins are used as general IO ports; When ENB is set to 1, the LCD controller is enabled.

They are the default counter values respectively. N-row front null pixel cloc

TVS main parameters of diodes--reprintThe best way to deal with the damage to the device by instantaneous pulses is to draw the instantaneous current from the sensitive device. The TVs diode is connected in parallel with the protected line on the circuit board, and when the instantaneous voltage exceeds the normal operating voltage of the circuit, the TVs diode has an avalanche that provides an ultra-low resistance path to the instantaneous current, which results in instantaneous current being i

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.

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
