Hi guys, this is my first post so please bear with me. I have come
across a problem which is stumping me so far. I have been provided two
clocking inputs ranging from 0 to 6.5kHz. I do not know what frequency
these operate at, and they are constantly changing. They also run at
different frequencies. I have to design a circuit to compare the two
inputs, and trigger off the fastest signal only. I am told it is easily
done with J-K flip flops but I have been looking at flip flops and
multivibrators for hours now and have not gotten any farther. Does
anyone have any ideas?
Homework ?:-)
Doesn't matter, although people get Brownie points for admitting it up front. But this guy claims it's his first post, so he doesn't know the rules.
If you think it's homework, give hints on how to approach the problem, not copiable solutions.
It's digital, so I am excused. (;-)
