produce nonlinear intermodulation distortion? The answer is yes! Although there is no systematic theoretical analysis, it has been found in engineerin...[Details]
LED lamps and bulbs are now rapidly replacing incandescent, halogen and CFL (compact fluorescent lamp) light sources in many general lighting applications. Flyback DC/DC converters are the power su...[Details]
introduction
At present, measuring instruments are developing towards networking, and each individual embedded instrument will become a node on the Internet. This system realizes the network...[Details]
At present, how various communication technologies will evolve after 3G is a focus of great concern in the industry. Especially for TD-SCDMA, whether it can achieve smooth evolution to the next gen...[Details]
1 Introduction
Ultrasound refers to elastic vibration with a frequency higher than the audible frequency limit (i.e., in the frequency band above 20 kHz). The propagation process of this vib...[Details]
In order to prevent the lithium battery from being damaged by abnormal conditions such as overcharge, over discharge, and overcurrent, a lithium battery protection device is usually used to prevent...[Details]
In industry, voltage 0…5 (10) V or current 0 (4)…20 mA is usually used as a method for analog signal transmission, which is also a method often used by programmable controllers. So what are the dif...[Details]
1. Tips for charging UPS for the first time
After purchasing a new UPS, plug the UPS into the 220V mains power grid and charge it for at least 12 hours to ensure that the battery is fully char...[Details]
In some motion control systems with simple control or low cost requirements, stepper motors are often used as actuators. The biggest advantage of stepper motors in such applications is that they ca...[Details]
For a long time, my country has implemented "community-style collective heating" for hot water heating, and settled accounts based on the heating area, regardless of whether the user uses heat. Thi...[Details]
