The number of speakers and their spacing limit the sound field of a portable stereo system.
Spatial audio attempts to artificially recreate the experience of listening to sounds i...[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]
1 Basic Features
In computer control systems and various intelligent instruments and meters composed of single-chip microcomputers (or microprocessors), various external analog signals must be ...[Details]
The above is to use MB1404 as a stereo composite signal transmitter. You can use the internal high-frequency amplifier and oscillator or not! According to my experience, I still recommend beginners...[Details]
Cars equipped with xenon headlights are already common on the road. Whether they are standard equipment on high-end cars or embellishments on modified cars, xenon lamps are gradually becoming a sym...[Details]
Every time I go home and walk up the stairs, I am always scared. The corridor lights are often broken, and no one changes the bulbs, or they are not smart enough and need to be operated manually. E...[Details]
1 Load Regulation
Changes in power supply load will cause changes in power supply output. When the load increases, the output decreases, and vice versa, when the load decreases, the output inc...[Details]
The capacity of a battery depends on the amount of charge and discharge, in addition to some factors of the battery itself. Obviously, if the charge and discharge of the battery can be recorded all...[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]
There are many types and styles of digital voltmeters in design and development. Traditional digital voltmeters have their own characteristics. They are suitable for manual measurement on site. Tra...[Details]
As a new type of centralized and decentralized elevator control system, serial communication has been widely used in China. Compared with the previous centralized and unified control system, each s...[Details]
In recent years, the application of single-chip microcomputer systems in the field of industrial measurement and control has become more and more extensive. However, for industrial sites with harsh...[Details]
