The question is shown in Figure 1. I can't figure out why the answer is drawn like that. Only analyze the situation where Rw2 is at the top. The question shows a sawtooth wave generator. Because the s...
I have an old TV. The original tuning circuit is old and the tuning voltage is unstable. Later, I removed the original potentiometer and replaced it with a volume potentiometer. It worked well at firs...
[color=#000][font=Arial, SimSun]Since the potential of point E does not change under the action of differential mode signal, it is equivalent to being connected to the "ground"; and since the potentia...
Smart charger: It adopts MICROCHIP, MCU chip design, and is designed for standard lithium battery charging. It adopts the typical lithium battery fast charging curve for charging, which can meet the r...
Measuring resistance with a Fluke multimeter The ohmmeter of a multimeter can measure the resistance of a conductor. The ohmmeter is represented by "Ω" and is divided into four ranges: R×1, R×10, R×10...

All electronic design engineers and scientists have performed electrical signal analysis, or signal analysis for short. Through this basic measurement, they can gain insight into signal details and...[Details]
In recent years, lighting has become an important area that countries around the world are targeting to promote energy conservation and environmental protection. According to statistics, about 20% ...[Details]
1. Introduction
At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]
I. Introduction
Since RS232 has a short communication distance (only 15 meters according to EAT/TAI-232 standard), and can only perform point-to-point communication, it cannot directly f...[Details]
Overview:
This paper introduces a method of connecting a CAN-bus network with Ethernet to form a medium-sized remote monitoring/data transmission network.
CAN (Controller Area Network) is ...[Details]
Many battery-powered systems require a visual indicator to show when the battery needs to be replaced. LEDs are commonly used for this purpose, but they consume at least 10mA of current. This con...[Details]
Digital array radar (DAR) uses digital beam forming (DBF) in both receiving and transmitting modes to achieve flexible distribution and reception of RF signal power in the airspace, obtain excellent t...[Details]
Nippon Electric Works and Volvo Technology Japan have developed a wireless power supply system for electric vehicles (EVs). Using this system, the two companies have successfully conducted an exper...[Details]
TC9012F is a universal CMOS large-scale integrated circuit for infrared remote control signal transmission, suitable for remote control of TV, VTR, laser player and other equipment. In the market, ...[Details]
Abstract: The output of high-range acceleration sensor is less than 10 mV under the excitation of small signal. The noise of traditional test system may cover such small voltage signal, so that hig...[Details]
Since AC mains power may experience power outages, voltage sags and surges, continuous undervoltage and overvoltage, and frequency fluctuations during supply, these factors will affect the continuous ...[Details]
