About thyristors used for DC switching.
I want to use a unidirectional thyristor as a DC switch. Is it possible? Use the high and low levels of the IO port of a 3.3V microcontroller to control the control end of the thyristor. Is it feasibl
How to measure continuous pulse width using VHDL? Take a look at my program
When there is no signal, the pulse is at a high level, and the signal to be measured is used as a gate signal. When measuring a low level, the highest bit of the data q outputs 0, and the remaining bi
