With the promotion of the construction of intelligent communities in the country, anti-theft systems have become essential equipment for intelligent communities. Especially in recent years, the urg...[Details]

Assume that data is read from 8-bit AD (if it is a higher-bit AD, the data type can be defined as int), the subroutine is get_ad(); 1. Limited secondary filtering /* A value can be adjust...[Details]

In early 2002, I started to write a working program for an IC card prepaid electricity meter. The meter used Philips' 8-bit 51-expanded single-chip microcomputer 87LPC764 , and wa...[Details]

Microcontrollers (MCUs), which are widely used in automotive electronics, are rapidly facing time and cost pressures. The main advantage of using MCUs has always been to create high-level system in...[Details]

Floating-point digital signal processing has become a constant requirement for precision technology, often in applications requiring high accuracy in areas such as aviation, industrial machinery, a...[Details]

Due to the significant increase in electronic devices in automotive and industrial applications, the automotive and industrial markets continue to play an important role in China's electronics in...[Details]

1 Introduction Solar street lights are mainly composed of four parts: solar photovoltaic cell components, batteries, charge and discharge controllers, and lighting fixtures. The bo...[Details]

Introduction Power subsystems are becoming more and more integrated into the overall system. Power systems have moved from being separate "essential dangerous devices" to being monitorable...[Details]

I. Introduction In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]

Power management solutions for today's portable application processors are becoming increasingly integrated. Total power consumption, standby and sleep current consumption affect battery size, bill...[Details]

With the continuous improvement of the requirements of intelligent building security systems and the continuous improvement of people's safety awareness, indoor anti-theft has gradually attracted peop...[Details]

General LED lighting has a current limiting resistor in the driving circuit, and the power consumed by the resistor has nothing to do with the LED light emission. In order to improve efficiency, a...[Details]

Overview In spectral measurement, photomultiplier tubes (PMT) and charge-coupled devices (CCD) are often used as photoelectric converters. PMT is used in slow-changing, high-precision spectral...[Details]

1. Disadvantages of choosing too high a voltage level Choosing too high a voltage level will result in too high an investment and a long payback period. As the voltage level increases, the...[Details]

We know that the inverter consists of two parts: the main circuit and the control circuit. Due to the nonlinearity of the main circuit (switching action), the inverter itself is a source of harmoni...[Details]
