if i have a digital signal that i want to recognize, i sample in the middle of the bit to know its a zero or one.
sampling in the middle can be done using a local clock that is 5 times faster than input rate, which results in each bit contains 5 local clocks and u can sample at the third local clock.
if there is sm amount of noise in my signal, it may result in 4.9 local clocks per bit which means an error in sampling after a certain amount of bits..
I want to draw a graph of my bit error rate vs noise/power for such a system. how?
if i have 4.9 clocks instead of 5, thats 2% noise. how much shall i consider No in this case?
thank you.
