There is something that I'm wondering. 74HC74's Q' pin connected to the other 74HC74's CLR but then doesn't Q' always become high no matter what? Even if there is a pulse swallow signal, neither Q will be high. Am I thinking wrong?
Edit: I just made a simulation in proteus and it worked. Can...
Thank you for your response! I am going to test it on wednesday. I'll post the results once I tested it. Also there is a symbol that I don't know on schematics. The one connected to the top pin of the top 74HC02 and to the data pin of the lower left 74HC74(a cross inside a circle). What does...
Does it matter if the amplitude of the phase-shifted signal changes a little as ɸ is varied?
It doesn't matter if amplitude changes if iit is a little change. if it is a big change I would need to change it back to 5V with something else.
You'd be happy with 180° shift in steps of 5°, because...
I am trying to create a phase sweeper at 31.4KHz(and constant 5V) for a small antenna array that consists 2 antennas. If I can create 2 signals with a frequency difference < 1Hz it's okay too(It will be nearly same) as long as I can control that difference because I need to change phase at a...
There was a question on my exam. There is a green filter and blue light is directed to the filter. Normally It should pass through the blue light but my teacher says that we wouldn't be able to see it so the color we see would be black but I think it would be blue. What is the answer?
Hi! I am making a physics project and I need to throw a ball to a target which is 5 meters ahead. I will use 2 counter rotating wheels to throw the ball but I have no idea what should motors torque or rpm should be. I tried to calculate it with determining the velocity first but the ball needs...
