I would like to ask the following questions: 1. What is the function of the part composed of C1, C2 and R1 in the figure? 2. What is the function of transistors Q1 and Q2? Thank you!...
Another question: What kind of transistor is used to drive this relay? How to explain the words "１０A/28VDC, 5A/220VAC, DC5V" on it? It has no requirements for the pull-in current?...
I guess it's a firmware library problem again, as shown in the following figureAn error occurred when setting the channel according to the user manual. I would like to ask how to set the external inte...
The following figure shows the simulation schematic diagram and simulation waveform of the boost circuit, which is built using PSIM software. The inductor parameters are 4mH, the capacitor is 10uF, th...
I would like to ask what the load current and load voltage in the book Circuit Design Based on Arithmetic Units and Analog Integrated Circuits mean. I can't understand why the simulation results I got...
As we all know, the 52 MCU has one more T2 timer than the 51. The car I recently built needs three timers, so T2 also comes in handy. It seems that there is not much information about T2. I read a boo...
