Hello Everyone..

 

I would like to ask it is written in a Technical Tutorial, that in a DDS there are always those bits that are truncated

in the process after the accumulator,because if so the look up table will be very large (for example 32bits word will lead to -4GBYTE-lookup table), my question is why is it a a problem to make this size of lookup table?

 

Thanks

Meir
