Help needed in VHDl code for calculating the I and Q phase component for a ADC signal

Hello all, I am designing a DDC in which I need to calculate the In phase(I) and the Quadrature phase(Q) components of my ADC signal. I know how these components are manually calculated from som...

Hi,

What I actually require is to calculate the I and Q phase components from the digital output(bits) that I obtain after performing the decimation by 8 process(according to DDC.jpg). The output of my VHDL code after the decimation by 8 process is digital. So, a method for decomposing the digital output to I and Q phase components (also in digital) would be a lot more helpful. Please help me out to solve my issue. Thanks in advance.

The I/Q you got is I/Q phase components. I am not clear what you are after.
