Hello,
I have a question that how the output coming out of PLL or DLL loop filter is utilised by the NCO to generate new frequency using the look-up table.
I have read it in books that NCO has a phase accumulator which coverts the output from the loop filter to some bits, and based on these bits we see the look-up table and find the corresponding frequency and phase value for these bits. And based on this frequency and phase the NCO would generate Sinusoid.
I fail to understand here that how does the phase accumulator converts the output of the loop filter to bits(1s and 0s). I need to know this because I have to use this NCO in a MATLAB program.
Thanks,
Priyanka
