Isn't the diode cut off when it is in reverse direction, equivalent to disconnected? Why is there voltage? When the diode is in forward and reverse direction, the voltage measured at 5V is almost the ...
Recently, the school required us to make a device for collecting ECG. When making a low-pass filter, we calculated through the formula that the cut-off frequency should be around 250HZ using 0.047uF a...
The schematic is as follows
The output voltage should be 5.18V.
But the actual output voltage is 9.7V.The output is connected to two LDOs to convert to 3.3VIf both are not disconnected, it will not be...
A: The kernel driver does not support higher versions of eMMC.
Is there a modified Android 4.4.2 kernel image that can be sent to me for testing?
B:
We have not updated 4.4.2, you can compile and modi...
As the signal rise time decreases and the signal frequency increases, the EMI problem of electronic products has also been paid more and more attention by electronic engineers. The success of high-spe...
[size=4] Integrated operational amplifiers are highly versatile active devices. They can be used not only for signal calculation, processing, transformation and measurement, but also for generating si...
