how to use xilinx dds
Hi
My question is about the Xilinx DDS
you can find it's details in this link
https://www.xilinx.com/support/documentation/ip_documentation/dds_ds558.pdf
my question is:
A hi resolution phase accumulator is used and then the phase is Quantized to low resolution before using it for the sine look up table,
Why We use high resolution Accumulator and then quantize it to low resolution?
why don't use a low resolution accumulator?
