I want to learn about the multiplier part, but I can't find the multiplier part in the routine of the development board. I have opened every routine and still can't find the multiplier. Is there any r...
I use quaratus2 to do waveform simulation. There is no problem with compilation and code, but the waveform cannot be simulated. It prompts the error code: Error: (vsim_3170) Could not find 'work.PPQ_v...
[b]Custom frame of signal generator[/b] [color=#000][size=15px]From the previous experimental purpose, we know that we need to use the serial port to control the parameters of the waveform. Generally ...
If a large capacitor is connected in series after an AC input, the output on the other leg of the capacitor will be the same as the AC input.If a large capacitor is connected in series after a DC inpu...
After the microcontroller is connected to the computer via a USB cable, the problem of "unrecognizable USB device" appears. I wanted to imitate Atom's one-click download circuit and make a minimum sys...
I. Introduction
In the field of power conversion, isolated converters (forward, flyback, and double-ended) with low output DC voltage all use MOSFET as the rectifier device. Since these devi...[Details]
