Once powered on normally, the chip Vref has a 5V reference voltage, which generates base current through r1, turns on transistor Q1, and generates collector current flowing through r2.

Seeing the forum activities, I was eager to learn MicroPython. I knew Python a long time ago, but I didn't learn it. Python is a scripting language that interprets and executes, and has great flexibil
The sound card obtains the sound analog signal from the microphone, and converts the sound wave amplitude signal into a series of digital signals through the analog-to-digital converter (ADC), which i
[size=4] To introduce the push-pull circuit, we first introduce some basic knowledge of the power amplifier. From the perspective of energy control, there is no essential difference between the power
I use ir2110 as a driver to make a single-phase full-bridge inverter circuit. Why do I have both high- and low-test outputs, and the waveform is stable, but I can't generate a sine wave when driving t
