Convert a complex stream to a real one at twice the rate

Started by System Alchemist May 28, 2008
Could someone pass mea pointer to how the GC1012 converts a complex 
output stream to a real one at twice the rate?

Similarly how it offsets the spectrum by one-fourth the Nyquist rate?

TIA!

Probably by mixing up by Fs/4.

Consider the sample values of a complex exponential at Fs/4... -- Oli
