As shown in the picture, I don't quite understand that OPA820 should play the role of comparator, right? My OPA820 output is ±4V, and the voltage of the voltage control terminal VG of VCA821 should be...
As the title says: Before running program P1, I want to first determine whether a process P2 is running. If P2 has just finished running, then run program P1. My programming environment is EVC4.0. Cou...
In recent years, PXI has established its position in the test and measurement industry, especially due to its features such as high-speed data transfer rate and small open and flexible PXI system. Thi...
If I want to make a shaping circuit to make the signal into a pulse signal with the same frequency, then can't I just pass the signal through an AND gate? For example, 74F08, the AND gate will only ou...
I use 149 single chip microcomputer and DAC5571 to synthesize sine wave, and use the table lookup method to synthesize, but I find that the output frequency is generally only a few hundred Hz at most,...
