I found an amplifier board and connected it to a 10W speaker, but I could hear obvious noise, so I wanted to use an oscilloscope to check the waveform of the audio signal. However, when I measured the...
[align=left][color=rgb(70, 70, 70)][size=3]In instant messaging applications, real-time voice communication between two or more parties is required. In situations with higher requirements, external sp...
In order to make AC power conversion convenient, usually industrial electricity, three sinusoidal AC. The current phase (reflecting the direction and magnitude of the current) differs by 120 degrees. ...
I want to use extended EEPROM to store historical data. Since there is no power-off detection part in my circuit, but I have to deal with the power-off situation, I want to know where I have saved aft...
[b][color=rgb(0, 0, 0)][font=宋体]We often see 0 ohm resistors in circuits. For novices, it is often confusing: since it is a 0 ohm resistor, it is a wire, why should it be installed? Are there any such...
The intelligent driving community has its own rhythm. Some are busy pushing new versions and focusing on R&D, others are busy with publicity and promotion, and still others are immersed in mass pro...[Details]
Flip-chip and ball grid array (BGA) are two widely used packaging technologies in the electronics industry. Each has its own advantages and limitations, and in some cases, they can complement each ...[Details]
New energy vehicles are increasingly popular with consumers due to policies and energy conservation. Once you've purchased your vehicle, maintenance is essential. However, due to the different powe...[Details]
