Hi geeks,

I have a requirement to generate a sine wave in the range 5Hz to 5 KHz using DAC.
I think the lookup table method matches my requirement.

But the problem which i am facing is that how to choose the number of samples for each frequency and the sampling interval.
I need to explain the logic why i choose the specific number of samples and the sampling interval.
could you guys please help me out..!!
